A pair of protons in an atomic nucleus repel each other,but they are also attracted to each other.Why?
A)The pair repel each other by nuclear force but attract one another by an electrical force.
B)The pair repel each other since they are both positively charges but they are held together by much stronger forces known as quarks.
C)The pair attract each other by nuclear force but also repel one another by a weaker electrical force.
D)Although it is known that protons repel each other at short distances because of like charge,it is not known what actually holds protons together in the nucleus because we have never seen the nucleus of an atom.

Protons repel each other due to their like positive charges, which is an electrical force. However, within the nucleus, they are attracted to each other by the strong nuclear force, which is much stronger than the electrical repulsion at very short distances, allowing the nucleus to remain intact.
