Gravity and electromagnetic force

compare and contrast these forces. also provide two ways that they are alike and two ways that they are different.

1) Gravitational force and electromagnetic force both are field forces which means both forces exerted from long range of distance and we do not require any physical contact to apply these type of forces.

2) Now we also know that

both the forces are inversely depends on the square of the distance between two charges or two masses

so both forces follow inverse square law.

Now two ways they are alike is

1) gravitational force never exist in form of repulsive force while electromagnetic force is either repulsive or attractive.

2) Gravitational force is independent of the medium between two masses while electromagnetic force is dependent on the medium between two charges

i think the answer is tomato juice? not entirely sure though
