Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Mass of proton, Mp=1.67265a.m.u
Mass of neutron, Mn=1.67495a.m.u
Both the statements are correct but the Reason is not the correct explanation of the Assertion.
Because the proton is a positively charged particle whereas neutron is neutral. Thus the positive charge of nucleus repels the proton while penetrating but not the neutron. Hence the penetrating power of neutron is more than that of proton.
