For a given lens, the magnification was found twice as large when as when the object was 0.15 m distance from it as when the distance was 0.2 m. Find power of the lens.

A

1.5 m

B

0.20 m

C

0.10 m

D

0.05 m

Text Solution

Verified by Experts

The correct Answer is:
C
`m=f/(u+f)" "therefore2=(-0.2+f)/(-0.15+f)" "thereforef=0.1m`
