The gravitational force of attraction provides the centripetal force. So you need to equate Fg and Fcentripetal (which you can just write as ma for this case).Rbethell16 said:

Gravitational force is a fundamental force of nature that describes the attraction between objects with mass. It is responsible for keeping planets in orbit around the sun, and objects on Earth from floating away into space.
The strength of gravitational force is calculated using the formula F = G(m1m2)/r^2, where G is the universal gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.
The strength of gravitational force is affected by the masses of the objects and the distance between them. The larger the masses and the closer the objects are, the stronger the gravitational force.
The gravitational force of Earth is unique to its mass and distance from other objects, just like every other planet in our solar system. However, the strength of Earth's gravitational force is stronger than that of smaller planets like Mars or Venus, and weaker than that of larger planets like Jupiter or Saturn.
No, gravitational force cannot be changed. It is a fundamental force of nature that is constant and universal. However, the effects of gravitational force can be counteracted by other forces, such as the force of thrust from a rocket ship launching into space.
