A capacitor with capacitance C=5uF and charge Q=20uC has a separation of d=1mm.
A) If a charge q=.2uC is placed at a distance d1=.4mm from the positive plate, what is the force on it?
B) If then the charge q=.2uC with a mass 1gram is released, which plate will it arrive on and what will be the speed when it arrives?
