Answer:
The new force becomes (1/9)th of the original force.
Explanation:
The gravitational force between two masses is given by :
Where
r is the distance between masses,
If the new distance is, r' = 3r
The new force is given by :
So, the new force becomes (1/9)th of the original force.
Here's the solution,
gravitational potential energy :
=》
where,
m = mass
g = acceleration due to gravity
h = height
So,
=》
=》
So, potential energy = 24.01 joules
