## Question

### Solution

Correct option is

5.0 cm

The situation is shown in figure. The radius of curvature of the mirror is r= 2f = 20 cm. Thus, the nearer end B of the rod AB is at the centre of the curvature and hence, its image will be formed at B itself.

We shell now locate the image of A.

Here u = –30 cm and f = –10 cm. We have

or

Thus, the image of A is formed at 15 cm from the pole. The length of the image is, 5.0 cm.
