Q. No.An object is placed at a distance of \(40~\text{cm}\) from a concave mirror of a focal length of \(15~\text{cm}.\) If the object is displaced through a distance of \(20~\text{cm}\) towards the mirror, the displacement of the image will be:
| 1. | \(30~\text{cm}\) away from the mirror. |
| 2. | \(36~\text{cm}\) away from the mirror. |
| 3. | \(30~\text{cm}\) towards the mirror. |
| 4. | \(36~\text{cm}\) towards the mirror. |

Column 1 Column 2
A. m=-2 a. Convex mirror
B. m=-1/2 b. Concave mirror
C. m=+2 c. Real image
D. m=+1/2 d. Virtual Image
