The focal length of convex lens is 10 cm. Its magnifying power when it is used as a magnifying glass to form the image at (i) near point and (ii) for point is

View answer and explanation

Correct option: A

3.5\,;\,2.5

Option A (

3.5\,;\,2.5

) is correct because the magnifying power is calculated using

m = 1 + \frac{D}{f}

for the near point and

m = \frac{D}{f}

for the far point.
