A compound microscope has two lenses. The magnifying power of one is 5...
Given:
Magnifying power of one lens = 5
Combined magnifying power = 100

To find:
Magnifying power of the other lens

Solution:

Let the magnifying power of the other lens be x.

The formula for the combined magnifying power of two lenses is:

Magnifying power = Magnifying power of lens 1 x Magnifying power of lens 2

Given that the combined magnifying power is 100, we can write:

100 = 5 x x

Solving for x, we get:

x = 100/5 = 20

Therefore, the magnifying power of the other lens is 20.

Hence, the correct answer is option B.
