Signs and symptoms. 1  Pain on the outer side of the thigh, occasionally extending to the outer side of the knee, usually constant. 2  A burning sensation, tingling, or numbness in the same area. 3  Multiple bee-sting like pains in the affected area. 4  Occasionally, aching in the groin area or pain spreading across the buttocks.
And the reason they don't is because of the strong nuclear force. In physics, there are four fundamental forces: gravity, the electromagnetic force, the weak force, and the strong force. The strong force is, unsurprisingly, strong. The strong force is the force that holds the nucleus of the atom together, even through other forces want to pull it apart. The electrostatic repulsion (part of the electromagnetic force) between the positive protons in the nucleus is very powerful.
Nuclear Force is defined as the force exerted between numbers of nucleons. This force is attractive in nature which binds protons and neutrons in the nucleus together. Since the protons are of same positive charge they exert a repulsive force among them.lectromagnetic force, gravitational force and strong nuclear force are the other forces. Weak Nuclear Force is caused by the emission or exchange of W and Z bosons. Weak nuclear forces are very short range because of the heaviness of the W and Z particles.
