A bird is flying with a velocity v between two long vertical mirrors making an angle `theta` with mirror `M_(1)` as shown. Then what will be the relative velocity of approach between the images formed by the mirrors due to the `1st` reflection in each of them

A

`v "sin"theta`

B

`2v"sin"theta`

C

`2(v"sin"theta + L)`

D

ZERO

Text Solution

Verified by Experts

The correct Answer is:
D

`implies v_(I)_(1)I_(2)= v_(I)_(2) - v_(I)_(1) = 0`
