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:

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

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:

A vector of modules a is turned through theta . Find the change in the vector

A vector vec A of magniude (A) is turned through an angle theta . Calculate the cahng in the magniude of vector.

A particle has co-ordinates (x, y). Its position vector makes on angle theta with positive x direction. In an infinitesimally small interval of time the particle moves such that length of its position vector does not change but angle theta increases by d theta . Express the change in position vector of the particle in terms of x, y, d theta and unit vectors hati and hatj .
