Calculate the force of earth's gravity on 1350kg spacecraft that is 1.28 * 10 ^ 6 * m above earth surface ( earth's mass is 6*10^ 24 kgg) .

The force of Earth's gravity is 327954 N

Explanation:

Given:

Mass of the space craft = 1350 kg

Mass of the earth = 6*10^ 24

Distance = 1.28 * 10 ^ 6

To Find:

The  force of Earth's gravity = ?

Solution:

The force of attraction between a planet and an object kept in space is given by the expression

where

M is the mass of the earth

m is the mass of the space craft

R is the distance between the earth and the space craft and

G is the gravitational constant

On substituting the values

F = 327954 N

a.) travels faster in solids because the particles are closer together.
