The graph in the given figure shows plot of variations of $v$ with change in $u$ for a concave mirror. Points plotted above the point P on the curve are for value of $v$:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Larger than 2f
At point P, u = v for concave mirror, which is distance of object at 2f from focal point.
Point plotted above are for value $v>2f$
