[b]1. A spherical dome of a Van der Graaff genenerator can be raised to a maximum electrical
potential of 600 kV; then additional charge leaks off in sparks as the electric field reaches 3.0
MV/m. Determine the charge and radius of the dome.
[b]2. Homework Equations [E=kq/r^2 and...
"The point charge is the same distance from all those charges.
The potential energy of a point charge q near another charge Q at distance r:-kqQ/r "
So in other words I should add up the charges (6Q) and then find the potential energy. Then relate potential energy to kinetic?
1. A point charge Q is held in the center of a charged ring. Half of the ring is charged
uniformly with charge 2Q and the other half with 4Q. When the point charge is released, it
accelerates toward infinitum. What is the ultimate speed of the point charge?
