A point object is moving with velocity v 0 = 2 i ^ - 3 j ^ + 4 k ^ in front of a moving plane mirror whose normal is along x - axis. The mirror is moving with velocity v m = i ^ - 4 j ^ + 2 k ^ . Find the velocity vector of image.

Options:

Answer:
B
Solution:

Let velocity of imagevi=x i^+y j^+z k^

Along the normal, i.e., along x-axis.

v im = - v om

⇒         x - 1 = - 2 - 1

⇒            x = 0

Along y and z - axes v i = v 0
