1. The problem statement, all variables and given/known data Two equally charged particles are held 3.2x10^-3 m apart and then released from rest. The initial acceleration of the first particles is observed to be 7.0m/s^2 and that of the second to be 9.0 m/s^2. If the mass of the first particle is 6.3x10^-7 kg , what are a.) the mass of the second particle, and b) the magnitude of the charge on each particle. 2. Relevant equations Coloumbs Equation 3. The attempt at a solution kinda need some help how to start this problem.
