Question

A satellite of mass m moves in a circular orbit at a distance of 3R from the center of the

Earth, as shown below. R is the radius of the Earth and g is the gravitational acceleration
at the surface of the Earth. What is the centripetal acceleration of the satellite?

Answer 1

Centripetal acceleration = Gm/9R²

Step-by-step explanation:

Given= mass of satellite = m

The radius of circular orbit = 3R

The formula for centripetal acceleration is

a = GM/R²

where G = gravitational constant

M = mass of satellite

R = radius of orbit

So by putting the values in given formula

we get = Gm/9R²

Key Concept= Centripetal acceleration-When a satellite moves in a circular orbit Gravitational force acts on it.

So centripetal force will be equal to gravitational force.
