Given that the universal gravitational constant is G=6.7×10-11 N m2/kg
If the radius of a planet is 6000.0km and its mass is 5.0×1024kg consider a satellite of mas 2500kg orbiting another 1000.0km above its surface and answer the questions below
a) Calculate the gravitational field strength (g) from the planet on the orbiting satellite. Ignore the satellite’s radius
b) What is the satellite’s ‘weight’ because of the nearby planet that it orbits around?

1. What is the gravitational potential energy of the mass (m) in the picture? The mass is the same
distance away r from the centers of both of the other masses, and both of the other masses have
the same mass, M. Give your answer in Joules.
r = 400 million meters
m = 7x1022 kg
м- 2х1027 kg
2. What is the net gravitational force for the mass m at this location? Give your answer in
Newtons.
f the semi-major axis, a, is measured in AU and the orbital period, p, is measured in years, then Kepler's 3rd law allows us to calculate the mass of the object they are orbiting using the following equation: M = a3/p2
Furthermore, the mass that is calculated by this equation is given in solar masses (MSun) where, by definition, the Sun's mass is 1 MSun.
Now, suppose I were to tell you that the mass of Jupiter is equal to 4.5e7 MSun.
Does the stated mass of Jupiter make sense?
Group of answer choices
Yes
No, it's too big.
No, it's too small
