Fg=Gm1m2/r^2
g=Gm/r^2
The Attempt at a Solution
I am having trouble finding a way to start. I can't set the g to 0 because that would not let me solve for radius.
It's late, and I'm not overthinking this but I do believe that the answer is: yes!Alameen Damer said:Do i make it so the forces of gravity equal to 0 or the accelerations of gravity equal to 0
But what will the acceleration due to Earth's gravity be there?Alameen Damer said:Ok so the forces of gravity must cancel out:
FgE=FgM
9.8m=gMm
gM must equal 9.8
9.8=Gm1/r^2
r=root(Gm1/9.8)
r=709685
Shouldn't that be the answer? As at that distance the g of the moon equals 9.8?
The force of gravity is 0 at the center of the Earth, since the gravitational forces from all directions cancel out.
Yes, at the center of the Earth the force of gravity is 0, but it is constantly changing and never stays at 0 for long.
No, gravity is a fundamental force of nature and cannot be turned off or manipulated.
No, the force of gravity will always exist on Earth as long as there is mass, which creates a gravitational pull.
The force of gravity varies on other planets depending on their mass and size. The larger the planet, the stronger the force of gravity will be.
