Question
Assertion: Unlike electric force and gravitational forces, nuclear force has limited range.
Reason: Nuclear force do not obey inverse square law.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Solution
B.
If both assertion and reason are true but reason is not the correct explanation of assertion.
Gravitational force:- Weakest force, but infinite range ( not part of standard model)
Weak Nuclear Force:- Next weakest, but short range
Electromagnetic Force:- Stronger, with infinite range
Strong Nuclear force:- strongest, but short range
