If I double the distance between two objects, what happens to their gravitational Force?

4x bigger

4x smaller

2x bigger

2x smaller

Two objects are attracted to each other with 125 N of gravitational force.

What would the force between them be if the distance between them were 5x bigger?

5 N

25 N

100 N

3125 N

Objects A and B each have a mass of 50M.

Object A exerts a gravitational force of 100 N on object B. Object A is then replaced by Object C and Fg becomes 50 N (assume objects B and C are the same distance apart).

25M

100M

$\frac{50M}{\sqrt[]{2}}$

$50M\sqrt[]{2}$

Imagine our friend David, who weighs 60 kg, is standing on the surface of our beautiful planet Earth (with a radius of 6.4x10⁶ m). Now, let's consider the mass of Earth, which is a whopping 6x10²⁴ kg! Can you figure out the proper setup for calculating the gravitational force acting on David?

$\frac{\left(6.67x10^{-11}\right)\left(60\right)\left(6x10^{24}\right)}{\left(6.4x10^6\right)^2}$

$\frac{\left(6.67x10^{-11}\right)\left(60\right)\left(6.4x10^6\right)}{\left(6x10^{24}\right)^2}$

$\frac{\left(6.67x10^{-11}\right)\left(60\right)\left(6x10^{24}\right)}{\left(6.4x10^6\right)^{ }}$

$\frac{\left(60\right)\left(6x10^{24}\right)}{\left(6.4x10^6\right)^2}$
