A proton and a neutron are each close to a positive nucleus. How does the charge on the nucleus affect the proton and the neutron, if at all?
A The neutron is attracted; the proton is repelled.
B The neutron is not affected; the proton is repelled.
C The proton is attracted; the neutron is repelled.
D The proton is not

Answer : The same charges will repel, since all protons are positively charged they will all repel so protons will repel. Neutrons don’t carry a charge so they can’t be repelled
So the answer is B: the neutron is not affected; the proton is repelled
