Question

A vector ā is rotated through an angle 0,
which is the magnitude of change in the
vector?​

Answer 1

Answer:

as a vector is rotated through an angle 0 then there will be no change in the magnitude of the vector. but if the angle of rotation will be greater than theta then there will be change in it. change is generally derived by the formula a b cos theta aur a b sin theta depending upon the angle.
