Describe the similarities and differences between the forces in a gravity field and electric field.                                                                                                                                       

The "shape" of the formula is the same (P) i.e. F = k × quantity 1 × quantity 2 (P)

                                                                                                r²

The constant is much bigger in an electric field (P)

The electric field can be both repulsive and attractive, whereas gravity is never repulsive. (P)
