An object appraches a convergent lens from the left of the lens with a uniform speed `5m//s` and stops at the focus. The image

A

moves away from the lens with a uniform speed 5m/s.

B

moves away from the lens with a uniform acceleration.

C

moves away from the lens with a pen - uniform acceleration.

D

moves towards the lens with a non - uniform acceleration.

Text Solution

Verified by Experts

The correct Answer is:
C
When object is at infinity then image will be formed on the other side of the lens of the focus. When object approaches focus then image moves towards infinity away from the lens. There is a nonlinear relation between object distance and image distance, hence the image will move away from the lens with a non-uniform acceleration.
The correct option is (c ).
