JEE PYQ: Ray Optics Question 12

Question 12 - 2021 (26 Feb Shift 2)

Given below are two statements: One is labeled as Assertion A and the other is labeled as Reason R. Assertion A: For a simple microscope, the angular size of the object equals the angular size of the image. Reason R: Magnification is achieved as the small object can be kept much closer to the eye than 25 cm and hence it subtends a large angle. In the light of the above statements, choose the most appropriate answer from the options given below:

(1) Both A and R are true but R is NOT the correct explanation of A

(2) Both A and R are true and R is the correct explanation of A

(3) A is true but R is false

(4) A is false but R is true
