#### Question

An object is kept on the principal axis of a concave mirror of focal length 10 cm. at a distance of 15
cm from its pole. The image formed by the mirror is:

(a) Virtual and magnified

(b) Virtual and diminished

(c) Real and magnified

(d) Real and diminished

#### Solution

Real and magnified

1/u + 1/v =1/f

u = -15, f = -10

:. v = -30

Is there an error in this question or solution?
