Assertion : Electrons do not experience strong nuclear force.
Reason : Strong nuclear force is charge-independent force.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true

Answer

B

Explanation

Nuclear force is a powerful attractive force acts as long as the distance between particles is within `10^(-15)` m. This force is charge independent. But as distance increases, the effect of nuclear force rapidly falls.
Electrons are distributed far away. The distance is beyond the range of the nuclear force. Hence nuclear force has no effect on electrons.
So, the assertion and reason both are true. But the reason does not explain the assertion.
