Question

Choose the correct option regarding the strength of Gravitational force.

• A. Gravitational force is the weakest amongst all the fundamental forces of nature.
• B. Gravitational force is approximately 10^-38 times the strength of the nuclear force
• C. Gravitational force has negligible influence when considered on an atomic scale.
• D. All of these

Answer 1

The correct option is D

All of these

The three fundamental forces are:

1. Gravitational forces

2. Nuclear forces

3. Electrostatic forces

Gravity is the weakest of the above fundamental forces of nature. The gravitational force is approximately ${10}^{-38}$ times the strength of the strong force (i.e. gravity is 38 orders of magnitude weaker), ${10}^{-36}$ times the strength of the electromagnetic force, and ${10}^{-29}$ times the strength of the weak force. As a consequence, gravity has a negligible influence on the behaviour of sub-atomic particles and plays no role in determining the internal properties of everyday matters.
