Question

Which one of the following is the weakest force?
A. Electrostatic force
B. Nuclear force
C. Electromagnetic force
D. Gravitational force

Answer 1

Hint: Here we have to examine each and every force to see which one is the weakest. It is the force which acts on the bodies irrespective of their mass. However, a bigger object can pull a smaller object towards its range due to this force.

Complete step by step answer:
Now let us see the options one by one-
Electrostatic force- Electrostatic force also known as the Coulomb force is the force between two electrically charged particles that is attractive or repulsive. Like charges repel each other and unlike charges attract each other. To measure the strength of the force between two charges, Coulomb’s law is used.
Nuclear force- The nuclear force acts between protons and neutrons. The power that connects the protons and neutrons in a nucleus together is the nuclear force. Between protons and protons, neutrons and protons or neutrons and neutrons, this force will occur. The nucleus is bound together by this force.
Electromagnetic force- A type of physical interaction that exists between electrically charged particles is the electromagnetic force. It operates between charged particles and is a blend of both electrical and magnetic forces. It may be attractive or repulsive to the electromagnetic force.
Gravitational force-The attraction force of all the masses of the universe; in fact, the attraction of the mass of the planet to the bodies near its surface is known as gravitational force.
On a smaller scale gravity is a very weak force. It pulls protons with a much smaller force than electrostatic force. On a larger scale the Sun holds all the planets in alignment with the help of gravitational force.
Hence, gravitational force is the weakest force.

So, the correct answer is “Option D”.

Note:
Gravitational force is a stronger force on a larger scale as it is able to attract the planets towards each other. However, it is a weaker force on a smaller scale. We don’t’ feel the pull of our earth whenever we walk on the surface of the earth. But this force can be massive in case of planets with high gravitational force like Jupiter, which can crush you with its gravitational force.
