Answer 1

Answer:

Correct option is

A

37.5 cm

The image formed by the plane mirror as well as by the convex mirror is at I.

Distance between object and plane mirror is (25−5)cm=20cm

∴ Distance between plane mirror and the image MI=20cm⟹PI=v=+15cm

Let the focal length of the convex mirror be fcm.

Using mirror formula,
