When a man and plane mirror both move towards each other at the rate of 10 m/s. At what rate the image approach the man ?

A

10 m/s

B

20 m/s

C

30 m/s

D

40 m/s

Text Solution

Verified by Experts

The correct Answer is:
C
When a person moves towards a mirror with velocity v, his image approaches the mirror with the same velocity v and the image approaches the person with a velocity 3v.
Thus, velocity of image `= 3v = 3 xx 10 = 30 m//s`
