Question

What is the approximate value of the gravitational force between a 73 kg astronaut and a 7.1×104 kg spacecraft when they're 89 m apart?

Answer 1

`F = 4.3671 * 10^(-8)\ Newtons`

Step-by-step explanation:

The gravitational force between two corpses is given by the following equation:

`F = GMm/d^2`

Where F is the force, G is the gravitational constant

(
`G = 6.67408*10^(-11)\ m^3kg^(-1)s^(-2)`), M and m are the masses of the corpses and d is the distance between them.

So we have that:

`F = 6.67408*10^(-11) * 7.1*10^4 * 73/89^2`

`F = 4.3671 * 10^(-8)\ Newtons`
