Object 1 has a mass of 10kg. object 2 has a mass of 10kg. the mass of object 1 is tripled and the mass of object 2 is doubled. what happens is the new force of gravity between the two objects?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
