Q1. Two equally charged, 1g spheres are placed with 2cm between their centers. When released, each begins to accelerate at 225m/s^2. What is the magnitude of the charge on each sphere?

Q2. We have pumped 20 bbls of fluid from the cement unit. But we think that we should have already achieved 425 psi at the unit. We are rigged up to do F.I.T and have already pressure tested all surface lines and there are no leaks.
