Where should a person stand straight from the pole of a convex mirror of focal length 2.0 m on its axis, so that the image formed become half of his original height?

A

`-2.60m`

B

`-4.0m`

C

`-5.0m`

D

`-2.0`

Text Solution

Verified by Experts

The correct Answer is:
D
Magnification of mirror
`m=(f)/((f-u))(1)/(2)=(200)/((200-u))`
`200-u-400`
`u=-200cm`
`=-2m`
