The graph shown part of variation of v with change in u for a concave mirror. Points plotted above the point P on the curve are for values of v

A

smaller than f

B

smaller than 2f

C

larger than 2f

D

larger than f but less than 2f

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) At P,u=v which is possible only when u=2f

If we take another pointQ just above P, then `vgt2f`.
