Identify the nature of the image formed when the object is placed at a distance of 20 cm from a concave mirror of focal length 10 cm.

$\huge \star \mathbb{ANSWER} \star$

$\fbox \pink{given: - }$

❥Object Distance = 20 cm

❥Focal Distance = 10 cm

$\fbox \green{formula used}$

$\small \implies \sf \frac{1}{f} = \frac{1}{v} + \frac{1}{u}$

$\fbox \blue{putting the formula}$

$\rightarrow \sf \frac{1}{ - 10} = \frac{1}{v} + \frac{1}{u}$

$\rightarrow \sf \frac{1}{v} = \frac{1}{20} - \frac{1}{10}$

$\rightarrow \sf \frac{1}{v} = \frac{1 - 2}{20}$

$\rightarrow \sf \frac{1}{v} = \frac{ - 1}{20}$

$\rightarrow \sf v = 20$

So...image will be real and imverted.
