An upright object is placed at a distance of $\displaystyle 40$ cm in front of a convergent lens of focal length $\displaystyle 20$ cm. A convergent mirror of focal length $\displaystyle 10$ cm is placed at a distance of $\displaystyle 60$ cm on the other side of the lens. The position and size of the final image will be:
Official answer
(2)
$\displaystyle 20$ cm from the convergent mirror, same size as the object
