What is the force of gravity (from the Earth) on the 700kg satellite if it’s 10km above the Earth's surface?

g = 4.7 × m/

Explanation:

Given that the mass of the satellite = 700 kg, and 10,000 m above the earth;s surface.

From Newton's second law,

 F = mg ............... 1

From Newton's gravitation law,

F = .................. 2

Where: F is the force, G is the gravitational constant, M is the mass of the first body, m is the mass of the second body, g is the gravitational force and r is the distance between the centers of the two bodies.

Equate 1 and 2 to have,

mg =

⇒   g =

But; G =  6.67 × N , M = 700 Kg, r = 10000 m

Thus,

g =

  =

  = 4.669 × m/

The force of gravity on the satellite is 4.7 × m/.

speed = 20/2 = 10 m/s
