An object is approaching a plane mirror at `10cms^(-1)`. A stationary observer sees the image. At what speed will the image approach the stationary observer ?

A

`10 cms^(-1)`

B

`5cms^(-1)`

C

`20cms^(-1)`

D

`15cms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
As is clear form figure. The distance of image with reference to observer reduces by `10cm` in one second.
