An object is placed at 15 cm from a convex lens of focal length 10 cm. Where should another convex mirror of radius 12 cm placed such that image will coincide with object.

A

18 cm

B

17 cm

C

14 cm

D

20 cm

Text Solution

Verified by Experts

The correct Answer is:
A

Image by lens:
`(10)/(d+12)-(1)/(-15)=(1)/(10)`
`(1)/(d+12)=(1)/(10)-(1)/(15)=(1)/(30)`
`d=18cm`
