Question

What is the gravitational acceleration of two object at distance equal to half times the radius of the moon from its centre if each object has a mass 12 kg​

Answer 1

Answer:

Newtons Law of Gravitation states that the force of gravity, F

g

, between two particles of mass m

1

and

m

2

has a magnitude of

F

g

=

d

2

Gm

1

m

2

where r is the distance between the center of the two masses and G is the gravitational constant.

In this case, the masses are doubled and the radius is halved. So the Force becomes

F

g

=

.

Hence, the new gravitational force will be 16 times more.
