Q. The graph shows variation of $v$ with change in $u$ for a mirror. Points plotted above the point $P$ on the curve are for values of $v$
A) Smaller then $f$
B) Smaller then $2f$
C) Larger then $2f$
D) Larger then $f$
Explanation
(c) At $P,\ u = v$ which happened only when $u = 2f$
At another point $Q$ on the graph (above $P$)
$v > 2f$
