a magnet has a north pole and a south pole. if you cut a magnet in half, what would you would have? a) two magnets, both with a north and south pole. b) two magnets but one would be stronger than the other. c) one magnet with a north pole and one with a south pole. d) no magnets since the original magnet would lose its magnetism
Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement - its motion. All types of energy can be transformed into other types of energy.
F = GMm/r^2
Where G is a constant, M is the mass of the larger object, m is the mass of the other object, and r is the distance between the two objects.
1600 = GMm/r^2
Now we can find the force when the distance doubles:
F = GMm/(2r)^2
GMm will remain the same since G is a constant and the masses didn't change, so the only difference between this and the first calculation is the denominator.
By simplifying the denominator, we find:
F = GMm/(4r^2)
Now we can see that the only difference between this and the equation given the original distance is that we are dividing by 4. This means that the force will be one fourth of the original force:
1600/4 = 400
The answer is 400.
