A convex lens of focal length f produces an image `(1)/(n)` times than that of the size of the object. The distance of the object from the lens is

A

nf

B

`(f)/(n)`

C

(n + 1) f

D

(n - 1) f

Text Solution

Verified by Experts

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