An object approaches a convergent lens from the left of the lens with a uniform speed of 5 m/s and stops at the focus. The image
1. moves away from the lens with a uniform speed of 5 m/s
2. moves away from the lens with a uniform acceleration
3. moves away from the lens with a non-uniform acceleration
4. moves towards the lens with a non-uniform acceleration
(3) Hint: The speed of the image depends on the speed of the lens.
When an object approaches a convergent lens from the left of the lens with a uniform speed of 5 m/s, the image moves away from the lens with a non-uniform acceleration.
