Question

Choose the correct options 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 the above.

Answer 1

The correct option is D All of the above.

The four fundamental forces are gravitational forces, strong nuclear force, weak nuclear force and 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 nuclear force, ${10}^{-36}$ times the strength of the electromagnetic force and ${10}^{-29}$ times the strength of the weak nuclear force. As a consequence, gravity has almost negligible influence on the behaviour of sub-atomic particles.
