An object 1.5 cm high is placed 10 cm from the optical centre of a thin lens. Its image is formed 25 cm from the optical centre on the same side of the lens as the object. The height of the image is

A

2.5 cm

B

0.2 cm

C

1.67 cm

D

3.75 cm

Text Solution

Verified by Experts

The correct Answer is:
D

`u=-10cm,v=-25cm,O=1.5cm,I=?`
`(I)/(O)=(v)/(u)`
`(I)/(1.5)=(-25)/(-10)impliesI=3.75cm`
