The sun’s gravitational force keeps the Earth and all the other solar system planets in a fixed orbit. Gravitational force does not need to be in contact to exert its downward force.

Detailed explanation-3: -Magnetic force, Gravitational force and Electrostatic force are non-contact forces.

Detailed explanation-4: -Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays.

Detailed explanation-5: -The correct option is D Frictional force Which of the following are non-contact forces? Magnetic force, Frictional force, Gravitational force, Electrostatic force.
