What is the force of gravity acting on a 2000 kg spacecraft when it is about the Earth at a in orbit distance of 8.375 x 106 m?

W = 13.44 KN

Explanation:

First, we need to find the value of acceleration due to gravity at the specified height:

where,

g' = value of acceleration due to gravity at given height = ?

g = value of acceleration due to gravity at surface of earth = 9.81 m/s²

h = height of space craft = 8.375 x 10⁶ m - 6.37 x 10⁶ m = 2.005 x 10⁶ m

R = Radius of Earth = 6.37 x 10⁶ m

Therefore,

Now, we can find the weight or force of gravity on space craft:

where,

W = Force of gravity on space craft = ?

m = mass of space craft = 2000 kg

Therefore,

W = 13.44 KN
