Question:

An object is placed at 10 cm distance in front of concave mirror of radius of curvature 15 cm. Find the position of the image.

Options:

60 cm

1 m

30 cm

10 cm

Correct Answer:

30 cm

Explanation:

u = -10cm , f = -7.5cm

$\frac{1}{v} = \frac{1}{f} - \frac{1}{u} = \frac{-1}{7.5} + \frac{1}{10} = \frac{-1}{30}$

$ \Rightarrow v = -30cm$
