write the source of centripetal force that are planet required to revolve around the sun

Answer»

The centripetal force required by a planet to remain in the orbit around the sun is provided by the gravitational force of attraction between the planet and the sun.

The centripetal force (F) depends on the radius (r) of the planets orbit, mass (m) of the planet and orbital speed (v) of the planet.

F = mv2/r
