Answer:
Force of gravity, F = 0.74 N
Mass of an object, m = 1.2 kg
Distance above earth's surface,
Mass of Earth,
Radius of Earth,
We need to find the force of gravity above the surface of Earth. It is given by :
R = r + d
R = 25370000 m
F = 0.74 N
So, the force of gravity on the object is 0.74 N. Hence, this is the required solution.
