A pair of parallel plates is charged by a 24-V battery.
(a) You move a particle with charge q from the positive to the negative plate. What is the change in the electrostatic potential (i.e., the potential difference)? What is the change in electrostatic potential energy if q = -3.0 oC? What if q = +3.0 oC?
(b) Continue with (a), how much work was required if q = -3.0 oC?
(c) If the particle has a mass of 10 g and charge q = -3.0 oC, you release it at the negative plate. What speed will it reach when it arrives at the positive plate?
(d) For an unknown charged particle, if you need to do a minimum +3.20x10-8 J work to move it from the positive plate to the negative plate, what is the sign of the particle? What is the amount of charge on the particle?
