Question

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 than $f$
• B. Smaller than $2f$
• C. Larger than $2f$
• D. Larger than $f$

Answer 1

Answer: (C)

At $P,u=v$ which happened only when $u$ $=2f$
At another point $Q$ on the graph (above $P)$
$v>2f$
