Detailed explanation-1: -The charging of the hair and attraction of paper bits towards it. Two magnets placed close to each other are also a non-contact force example. The freefall of a ball towards earth is by virtue of gravity. Leaves falling from a tree is an example of non-contact force.

Detailed explanation-2: -Explanation: 1 Mark. A non-contact force is a force applied to an object by another body that is not in direct contact with it. Ex: Gravitational force, Electrostatic force, Magnetic forces. They are non contact forces because they can influence the objects without being in contact.

Detailed explanation-3: -Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.

Detailed explanation-4: -Gravity. Is gravitational force a non contact force? Electrostatic force. The electric force is very similar to gravity, the difference here being that the gravitational force acts between the mass and the electric force acting between the two charged bodies. Magnetic force.

Detailed explanation-5: -Gravitational force. Electrostatics. Magnetic force. 27-Oct-2021
