False. Electromagnetic and Gravitational forces can overcome .
Natali5045456 [20]3 years ago

Answer:

True

Explanation:

The strong nuclear force is at times more rapidly than the electromagnetic force (EM). In essence, this can be given by the relationship:

\frac{1}{r^{-7} } instead of \frac{1}{r^{-2} }

Therefore, the strong proton – proton repulsion between two atoms with smaller radii is able to overcome to overcome non-charge forces, in this case, the gravitational and electromagnetic forces.

Protons and neutron exist of quarks. It requires a strong magnetic force to overcome the strong residual repulsion between two protons.
