Q. If an object moves towards a plane mirror with a speed $v$ at an angle $\theta$ to the perpendicular to the plane of the mirror, find the relative velocity between the object and the image
A) $v$
B) $2v$
C) $2v\cos\theta$
D) $2v\sin\theta$
Explanation
(c) From figure it is clear that relative velocity between object and it’s image $= 2v\cos\theta$
