Question

1 point
10 cm
20 cm
30 cm
35 cm

Answer 1

Answer:

30 cm

Explanation:

For a concave mirror, image size is same as the object size when it is placed at the center of curvature. Since radius of the mirror is twice the focal length, center of curvature lies at a distance of 30 cm from the pole. Hence, an object kept at 30 cm will produce an image of the same size as that of the object.
