A point object is placed infront of a plane mirror as shown in figure.
`X_(OM)impliesx`- co-ordinate of object relative to mirror
`X_(IM)impliesx-` co -ordinate of image relative to mirror
`X_(IM)=-X_(OM)`
differentiating `V_(1M)=-V_(OM)`
`V_(I)-V_(M)=-(V_(0)-V_(M))`
Velocity if image relative to mirror = velocity of object relative to mirror.
basing on this information answer the question

Two bodies A and B are moving towards a plane mirror with speeds `V_(A)` and `V_(B)` respectively as shown in fig. The speed of image of A with respect to the body B is

A

`V_(A)+V_(B)`

B

`V_(A)-V_(B)`

C

`sqrt(V_(A)^(2)+V_(B)^(2))`

D

`sqrt(V_(1)^(2)-V_(B)^(2))`
