Answer:
11121.19 kg
Step-by-step explanation:
Given that,
the gravitational force between Earth and the telescope is

Mass of the Earth is

The center of the Hubble space telescope is 6940 km from Earth’s center.
We know that, the force of gravity is given by the formula as follows :

m is mass of telescope and M is mass of Earth
So,

So, the mass off the telescope is 11121.19 kg
