These solutions for Physics And Mathematics are extremely popular among Class 11 Science students for Physics Physics And Mathematics Solutions come handy for quickly completing your homework and preparing for exams. A vector is defined by its magnitude and direction, so a vector can be changed by changing its magnitude and direction.

If we rotate it through an angle, its direction changes and we can say that the vector has changed. No, it is not possible to obtain zero by adding two vectors of unequal magnitudes. Yes, it is possible to add three vectors of equal magnitudes and get zero.

Consider the figure below: Lets examine the components of the three vectors. A zero vector has physical significance in physics, as the operations on the zero vector gives us a vector.

Similarly, the velocity vector of the stationary body is a zero vector. When a ball, thrown upward from the ground, falls to the ground, the displacement vector is a zero vector, which defines the displacement of the ball. Yes we can add three unit vectors to get a unit vector. No, the answer does not change if two unit vectors are along the coordinate axes. Yes, there are physical quantities like electric current and pressure which have magnitudes and directions, but are not considered as vectors because they do not follow vector laws of addition.

Two forces are added using triangle rule, because force is a vector quantity. This statement is more appropriate, because we know that force is a vector quantity and only vectors are added using triangle rule. No, we cannot add two vectors representing physical quantities of different dimensions.

However, we can multiply two vectors representing physical quantities with different dimensions. Yes, a vector can have zero components along a line and still have a nonzero magnitude. This vector has zero components along a line lying along the Y-axis and a nonzero component along the X-axis.

The magnitude of the vector is also nonzero. This is because the left hand side of the given equation gives a vector quantity, while the right hand side gives a scalar quantity.

However, if one of the two vectors is zero, then both the sides will be equal to zero and the relation will be valid. A vector is defined by its magnitude and direction. If we slide it to a parallel position to itself, then none of the given parameters, which define the vector, will change.

If we slide it parallel to itself, then the direction and magnitude will not change. The third vector of length 2 should lie along x axis. All the given options are incorrect. The component of a vector may be less than, greater than or equal to its magnitude, depending upon the vector and its components. We can determine this direction using the right hand thumb rule.

Here, 2. So, the answer must be written in three significant digits. However, components of a vector depend on the orientation of the axes. The x -component of the resultant of several vectors cannot be greater than the sum of the magnitudes of the vectors. First, we will find the components of the vector along the x -axis and y -axis.

Then we will find the resultant x and y- components. First, let us find the components of the vectors along the x and y -axes.

Consider that the queen is initially at point A as shown in the figure. Let AB be x ft. According to the polygon law of vector addition, the resultant of these six vectors is zero. A regular polygon has all sides equal to each other.

We know that the dot product of two perpendicular vectors is zero. Also, the direction of this product remains constant. According to the problem, the net electric and magnetic forces on the particle should be zero.

To find a slope at any point, draw a tangent at the point and extend the line to meet the x -axis. The required area can found by integrating y w. The metre scale is graduated at every millimetre. Hence, the number of significant digits may be 1, 2, 3 or 4. Its value is greater than 5.

So, the next two digits are neglected and 4 is increased by one. Therefore, the result should have three significant digits, while the other digits should be rounded off. So, the effective length should contain only two significant digits. Page No Answer: Yes. Answer: No, it is not possible to obtain zero by adding two vectors of unequal magnitudes.

A list of the major formulas used in vector computations are included. All of the vectors must be of the same type of quantity! For example, you cannot add a displacement to a velocity. The concept of vectors is discussed. In this case, vector will be positioned with its tail at the origin and its tip at the point 0, The negative of a vector is defined as the vector that, when added to the original vector, gives a resultant of zero! In mathematics, physics and engineering, we frequently come across with both types of quantities, namely, scalar quantities such as length, mass, time, distance, speed, area, volume, temperature, work, money, voltage, density, resistance etc.

Chapter List. If the two forces 4N and 3N acting simultaneously on a particle are in opposite direction, the resultant force F 1 is minimum. Let R be the resultant force, then,.

So let's suppose that we call it South. If she started south, then upon making a right-hand-turn, she is now heading west. And after making a second right-hand-turn, she is heading North. The diagram at the right depicts the physical situation. The Pythagorean theorem can be used to determine the magnitude of the resultant.

Vectors are added by a head-to-tail method and the resultant is drawn from the tail of the first vector to the head of the last vector. The diagram should indicate the relative distances and directions for each segment of the path. A worksheet can be ready for any subject. Definitions, formulas, examples with solutions.
