Aspace probe is launched from earth headed for deep space. at a distance of 10,000 miles from earth's center, the gravitational force on it is 600lb. what is the size of the force when it is at each of the following distances from earth's center? . a] 20,000 miles. b] 30,000 miles. c] 100,000 miles

A)The size of the force when it is at 20,000 miles from earth center is 150 lb.

B) The size of the force when it is at 30,000 miles from earth center is 66.66 lb.

C) The size of the force when it is at 100,000 miles from earth center is 6 lb.

Explanation:

The Gravitational force is given as:

G= gravitational constant

= masses of two objects exerting force on each other.

r = distance between the two objects

From the above expression it will be correct to write:

A) when the distance between the earth and space probe is 20,000 miles.

The size of the force when it is at 20,000 miles from earth center is 150 lb.

B) when the distance between the earth and space probe is 30,000 miles

The size of the force when it is at 30,000 miles from earth center is 66.66 lb.

C) when the distance between the earth and space probe is 100,000 miles

The size of the force when it is at 100,000 miles from earth center is 6 lb.

where are the vectors ?

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
