What is the gravity of a 10 kg body at a height equal to 2 Earth radii?

What is the gravity of a 10 kg body at a height equal to 2 Earth radii? Consider the acceleration of gravity on the surface of the Earth equal to 10 m / s ^ 2.

To find the force of gravity acting on the specified body, we apply the formula: Ft = G * Mz * mt / (Rz + h) ^ 2 = G * Mz * mt / (Rz + 2Rz) ^ 2 = G * Mz * mt / ( 3Rz) ^ 2 = mt * g / 9.

Constants and variables: mt – body weight (mt = 10 kg); g – acceleration of gravity (according to the condition g = 10 m / s2).

Calculation: Ft = mt * g / 9 = 10 * 10/9 = 11.1 (1) N.

Answer: The force of gravity is 11.1 (1) N.
