The reflection surface of a plane mirror...



The reflection surface of a plane mirror is vertical. A particle is projected in a vertical plane which is also perpendicular to the mirror. The initial velocity of the particle is 10 m/s and the angle of projection is `60^(@)`. The point of projection is at a distance 5 m from the mirror. The particle moves towards the mirror. Just before the particle touches the mirror, the magnitude of relative velocity of approach of the particle and its image is

A

10 m/s

B

5m/s

C

`10sqrt(3)m//s`

D

`5sqrt(3)m//s`
