The center of the Hubble space telescope is 6940 km from Earth’s center. If the gravitational force between Earth and the telesc
ope is 9.21 × 104 N, and the mass of Earth is 5.98 × 1024 kg, what is the mass of the telescope? Round the answer to the nearest whole number
2 answers:
The gravitational attraction between the Earth and the Hubble telescope is given by:

where
G is the gravitational constant
M is the Earth's mass
m is the Hubble mass
r is the distance of the Hubble telescope from the earth's center
By rearranging the equation and substituting the numbers given by the problem, we find the mass of the telescope:
