Question

There are four basic forces in nature: gravity, the electromagnetic force, the strong nuclear force, and the weak nuclear force. Of the four basic forces which acts over the shortest distance?

A gravity
B electromagnet force
C strong nuclear force
D weak nuclear force

Answer 1

C - Strong Nuclear force

Answer 2

D. Weak Nuclear Force.

Weak Force is named thus because it is weak compared to the Strong Force. However, it is responsible for holding particles that are smaller than a Proton. Hence, this is the force that acts over the shortest distance, typically of the order of
`10^(-18)  m`, which is much less than the diameter of a proton.
