NEET Physics Mirrors MCQ Question with Solution

A concave mirror has a focal length of 20 cm. If an object is placed 30 cm from the pole of the mirror, what is the nature and position of the image formed?

A

Real, inverted, 60 cm from the mirror

B

Virtual, upright, 60 cm from the mirror

C

Real, inverted, 12 cm from the mirror

D

Virtual, upright, 12 cm from the mirror

Correct Answer

Option A

Detailed Explanation

Using the mirror formula $\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$ where $f = -20$ cm and $u = -30$ cm, we find $v = -60$ cm. This indicates a real, inverted image 60 cm from the mirror.
