In each case shown, a particle of charge +q is placed a distance d from a particle of charge +4q. The particles are then released simultaneously. The masses of the particles are indicated in the diagram. Case 1 Case 2 A B C D +q, m O - - -- -. O +4q, m +q, mo - - - - O +4q, 3m d Rank the magnitude of the acceleration of each particle just after it is released. Explain your reasoning
