Question

An object approaches a convergent lens from the left of the lens with a uniform speed 5 $m ^ { - 1 }$ and stops at the focus. The image:

• A. Moves away from the lens with an uniform speed 5m^-1
• B. Moves away from the lens with an uniform
• C. Moves away from the lens with a non - unifrom acceleration
• D. Moves towards the lens with a non- unifrom acceleration

Answer 1

Answer: (C)

Moves away from the lens with a non - unifrom acceleration

Answer 2

: When an object approaches a convergent lens from the left of the lens with a uniform speed of $5 \mathrm {~ms} ^ { - 1 }$the image away from the lens with a non –uniform acceleration.
