Which is the weakest of the four fundamental forces? strong nuclear weak nuclear electromagnetic gravitational

Gravitational force is the weakest of the four fundamental forces .

Explanation:

Strong Nuclear force, Weak Nuclear force, Electromagnetic force and Gravitational force are the four fundamental forces of nature.

>The weak and strong nuclear forces are effective only over a very short range and dominate only at the level of subatomic particles. Gravity and Electromagnetic forces have infinite range.

If we consider interaction strength of gravitational force to be 1 unit then relative strength of other forces are

1. Gravitational force - unit

2. Weak Nuclear force - unit

3. Electromagnetic force - unit

4. Strong Nuclear force -   unit

Thus gravitational force is the weakest force out of four fundamental forces.
