Q. No.The lens combination, as shown in the figure, consists of two lenses, \(L_1\) and \(L_2\), of the focal lengths \(+10~\text{cm}\) and \(-10~\text{cm},\) respectively. The position of the image formed is:
1. \(60\) cm to the right of the concave lens
2. \(20\) cm to the left of the concave lens
3. \(60\) cm to the left of the concave lens
4. \(30\) cm to the right of the concave lens
1. \(60\) cm to the right of the concave lens

An object is placed on the principal axis of a concave mirror at a distance of \(1.5f\) (\(f\) is the focal length). The image will be at:
| 1. | \(-3f\) | 2. | \(1.5f\) |
| 3. | \(-1.5f\) | 4. | \(3f\) |
