Focal length of a convex lens is 20 cm and its RI is 1.5. it prodcued an erect , enlarged image if the distance of the object from the lens is

A

40 cm

B

30 cm

C

15 cm

D

20 cm

Text Solution

Verified by Experts

The correct Answer is:
C
Given `f=20cm`
If `|u|ltf` erect and enlarged image will be formed by convex lens. So, `u=15cm` is correct.
