A point object is moving with a speed v before an arrangement of two mirrors as shown in figure.

Find the velocity of image in mirror `M_(1)` with respect to image in mirror `M_(2)`

A

2v sin (`theta`/2)

B

v sin (`theta`/2)

C

2v cos (`theta`/2)

D

v cos (`theta`/2)

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Velocity of image , `v_(r)=sqrt(v^(2)+v^(2)-2vcdotvcdotcostheta)`
=2v`sin(theta//2)`
