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.

Options

A. `upsilon`
B. 2`upsilon`
C. `2 upsilon " cos" theta`
D. `2 upsilon sin theta `

Answer

C

Explanation

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