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 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 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 .

Position vector and a vector in terms of position vectors of its end points

Let veca, vecb,vecc be unit vectors, equally inclined to each other at an angle theta, (pi/3 lt theta lt pi/2) . If these are the poisitions vector of the vertices of a trinalge and vecg is the position vector of the centroid of the triangle, then:
