A vector of magnitude b is rotated through angle `theta`. What is the change in magnitude of the vector?

A vector of magnitude a is turned through angle theta . The magnitude of change in the vector is given by:

What is the magnitude of a unit vector ?

A vector of length l is turned through the angle theta about its tail. What is the change in the position vector of its head ?

A vector of length l is turned through the angle theta about its tail. What is the change in the position vector of its head ?

A vector of length l is turned through the angle theta about its tail. What is the change in the position vector of its head ?

A vector vecA is rotated through angle theta about its tail. Change of position vector of its tip of is:

What will be the angle between two vectors of equal magnitude for their resultant to have the same magnitude as one of the vectors?

When two vectors of magnitudes P and Q are inclined at an angle theta , the magnitudes of their resultant is 2P. When the inclination is changed to 180^(@)-theta , the magnitudes of the resultant is halved. Find the ratio of P and Q .
