GENERAL KNOWLEDGE

Detailed explanation-1: -Therefore, clearly from the above discussion we can see that magnetic force, electrostatic force and gravitational force are all three non-contact forces . The only left force is muscular force. This means that muscular force is not a non-contact force.

Detailed explanation-2: -Out of the given forces, electrostatic force and Gravity don’t require any contact to show their effect. Hence they are non-contact forces.

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: -A force that can cause or change the motion of an object by touching it is called Contact Force. For example, muscular force, frictional force, spring force, tension force, air resistance force etc.

Detailed explanation-5: -Gravitational force. Magnetic force. Electrostatics. The nuclear force-(there are two types of strong and weak nuclear force).
