Question

What is the force of gravity between a 9kg space rock and a 12kg space rock located 2m away from each other? Do not include G in your calculations. (For this reason, your answer will not be in newtons, but in G-newtons).

a) 108 G-newtons
b) 216 G-newtons
c) 36 G-newtons
d) 72 G-newtons

Answer 1

The force of gravity between a 9kg space rock and a 12kg space rock located 2m away from each other is 108 G-newtons.

Step-by-step explanation:

The force of gravity between two objects can be calculated using Newton's law of gravitation:

F = G * ((M1 * M2) / (R^2))

Where F is the force of gravity, G is the gravitational constant, M1 and M2 are the masses of the objects, and R is the distance between the objects.

In this case, the masses are 9kg and 12kg, and the distance is 2m.

Plugging these values into the equation, we get:

F = G * ((9kg * 12kg) / (2m^2))

Since we are not including G in our calculations, we can eliminate it:

F = (9kg * 12kg) / (2m^2)

Calculating this, we get:

F = 108 G-newtons
