A concave mirror of focal length f produces an image n times the size of the object. If the image is real then the distance of the object from the mirror is

A

`(n-1)f`

B

`(n+1)f`

C

`(n+1)f//n`

D

`(n-1)g//n`

Text Solution

Verified by Experts

The correct Answer is:
C
`(C) - n = (-f)/(-f-u)` (u coodinate)
`|u|=((n+1)f)/(n)`.
