An object 15cm high is placed 10cm from the optical center of a thin lens. Its image is formed 25cm from the optical center on the same side of the lens as the object . find the height of image

A

`2.5 cm`

B

`0.2 cm`

C

`16.7 cm`

D

`37.5 cm`

Text Solution

Verified by Experts

The correct Answer is:
