Define muscular force, electrostatic force and gravitational force. Give one example of each.

Hint: Here, we have to study the concept of forces like muscular force, electrostatic force and gravitational force and also study their examples where we feel these forces in our day to day life. We will explain each force with its definition and examples.

Complete answer:
Muscular force: This is the kind of force which is applied by the muscles of human beings or animals to do some kind of activities like pushing, pulling, hitting, etc. For example: an elephant holding a log of wood, a boy pushing away the block.

Electrostatic force: The force acting between charged and uncharged conductors is known as the electrostatic force. This force is a weak kind of force and is transferable between the charged to uncharged conductors. For example: when an ebonite rod is rubbed on silk cloth and then placed over some distance on the pieces of paper, the pieces are attracted towards the rod. The reason is the formation of electrostatic charge on the rod and electrostatic force between the paper and rod.

Gravitational force: The force acting on the body by the earth is known as the gravitational force. It is also known as the weakest force. The reason we can stand on the ground is because of the gravitational force. For example: the force of attraction between any object and the surface of earth is gravitational force.

Note:Here, we understand the concept of all the forces and concluded that the force acting by muscles of the animals is muscular, force between two or more charges is electrostatic and the force between the object and the planet is gravitational.
