A 610 kg satellite orbits at a distance from the Earth's center of about 5.3 Earth radii. What gravitational force does the Earth exert on the satellite?
M*g*(1/5.3)^2 = ____ newtons
The last "inverse square" term is the factor by which the weight is reduced due to the the large distance from Earth.
Plug in M and g and perform the calculation.
