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)            \[2v\sin \theta \]

Correct Answer: C

Solution :

                   From figure it is clear that relative velocity between object and it's image = 2v cosq
