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

Answer»

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 :Strong nuclear force is charge independent and acts EQUALLY between a proton and a proton, a NEUTRON and a neutron, and a neutron, and a proton and a neutron. It is responsible for the stability of nuclei and its range is `10^(-15)m`. Since ELECTRONS are present outside the nucleus. Hence, they do not experience strong nuclear force.
