Select all that apply. A beta particle: is electromagnetic energy is an electron has zero charge has zero mass has a + 2 charge has a - 1 charge

The force between two objects each of charge + Q Is measured as + F when the objects are separated distance d apart. If the charge on each object is double determine the new force between them a) + 2F b) + 4F c) + 1/2F d) + 1/4F
