to point charges
What is the electric potential at a point that is
3.0cm from a fixed particle of charge 6.0mC?
How much work must we do in order to move a particle of charge 3.0mC from
infinity to that point?
What is the potential at point P, located at the
center of the square of point charges. Assume that the distance of
a side is 1.3m and the charges are each 12nC.
8 point charges (each has a charge Q) are equally
spaced and fixed around a circle of radius R. What are the electric
potential and electric field due to the charges at the center of the circle?
(Assume that the reference point is at infinity.)
