A beam of light passing through a diverging lens of focal length $0.3$ $m$ appear to be focused at a distance $0.2$ $m$ behind the lens. Find the position of the object.

a) The position of the image is found by using the formula

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

By applying the value of

$f$ and

$u$

The position of the image is

$cm$ in front of the mirror.

The sign indicates the image is formed in front of the mirror.
