An object is placed 25 cm from a convex lens whose focal length is 10 cm . The image distance is ___________ cm.

A

50

B

16.16

C

6.66

D

10

Text Solution

Verified by Experts

The correct Answer is:
B
`1/f =1/v -1/u implies 1/v =1/f +1/u =1/(10) +(1)/(-25) =1/(10) -1/(25)`
`1/v =(15)/(250), v=(250)/(15) =(50)/(3) = 16.66 cm`
