If an object moves towards a plane mirror with a speed v at an angle `theta` to the perpendicular to the plane of the mirror, find the relative velocity between the object and the image.

A

`upsilon`

B

2`upsilon`

C

`2 upsilon " cos" theta`

D

`2 upsilon sin theta `

Text Solution

Verified by Experts

The correct Answer is:
C

Relative velocity between the object and the image.
`= v cos theta + v cos theta = 2v cos theta . ` ( as `v_(0) = v_(1) = v)`
