An object is placed beyond the centre of curvature C of the given concave mirror. If the distance of the object is $\displaystyle \mathrm{d}_1$ from C and the distance of the image formed is $\displaystyle \mathrm{d}_2$ from C, the radius of curvature of this mirror is :
Official answer
(3)
$\displaystyle \frac{2 \mathrm{~d}_1 \mathrm{~d}_2}{\mathrm{~d}_1-\mathrm{d}_2}$
