Question

4. A rocket moves away from the surface of Earth. As the distance r from the center of the
planet increases, what happens to the force of gravity on the rocket?

A) The force increases directly proportional to r^2

B) The force doesn't change.

C) The force becomes zero after the rocket loses the contact with Earth.

D) The force decreases inversely proportional to I/r^2​

Answer 1

Answer:

option d

Explanation:

the force of gravity is represented as

F = GM1M2/r²

now the mass of warth and rocket is considered to be constant and G is a universal constant so it can be said

F is inverse to r²

therefore as the value of r increases that is distance between earth and rocket increases the force decreases

(Follows inverse square law)
