Question

Inside nucleus, protons are held together though they have the same charge. Why?

• A. The strong attractive nuclear force far exceeds the electrostatic force between the protons
• B. Neutrons prevent them from repelling from each other
• C. The electrostatic attractive force between an electron and a proton is more than the electrostatic repulsive force between the protons
• D. Gluons are responsible for holding them together

Answer 1

The correct option is A The strong attractive nuclear force far exceeds the electrostatic force between the protons

$\begin{array}{c}\text{Protons are held together by the strong attractive}\\ \text{nucleur force that binds together protons and}\\ \text{neutrons. It acts only over very short-typically}\\ \text{nucleur distance.}\end{array}$
