Question

What is the force of gravity acting on an object at 20,000 meters above the Earth’s surface?​

Answer 1

Answer:

Fgrav = m*g

where d represents the distance from the center of the object to the center of the earth. In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.
