Question

An object is placed on the principal axis of a concave mirror of focal length 10 cm at a distance of 3.0cm from the pole. Then the position and Nature of the image is​

Answer 1

Answer:

15cm

Explanation:

Soln :-. Given u = -10cm , v= ? , f = -15cm

Applying mirror's formula,1/v +1/u = 1/f

1/v + 1/-10 = 1/-15

1/v = -1/15 + 1/10

=(-2+3)/30

= 1/30

V = 30 cm.

Hence, we get enlarged image, virtual in nature having magnification 3.
