A Man is Looking at a Small Object Placed at His Near Point. Without Altering the Position of His Eye Or the Object, - Physics

MCQ

A man is looking at a small object placed at his near point. Without altering the position of his eye or the object, he puts a simple microscope of magnifying power 5 X before his eyes. The angular magnification achieved is

• 5

•  2.5

•  1

• 0.2

Solution

1

We have :

h = Object height

u = object distance = 25 cm

D = Near point = 25 cm

Now,

m = (h/u)/(h/D)

⇒ m = (h/u)/(h/25)

⇒ m = 1

Is there an error in this question or solution?
