Question:medium
A point object is placed at a distance of $60\, cm$ from a convex lens of focal length $30\, cm$. If a plane mirror were put perpendicular to the principal axis of the lens and at a distance of $40\, cm$ from it, the final image would be formed at a distance of :

- 20 cm from the lens, it would be a real image.
- 30 cm from the lens, it would be a real image.
- 30 cm from the plane mirror, it would be a virtual image.
- 20 cm from the plane mirror, it would be a virtual image.
