Question

A point object is placed at a distance of 30 cm from a convex mirror of focal length 30cm. The image will form at

Options:

A . Infinity

B . 15 cm infront of the mirror

C . Pole

D . 15 cm behind the mirror

Answer: Option D
:
D
u=-30 cm, f =+30 cm,by using mirror formula

\frac{1}{f} = \frac{1}{v} + \frac{1}{u} \Rightarrow \frac{1}{+ 30} = \frac{1}{v} + \frac{1}{(- 30)}

v=15 cm, behind the mirror
