Charge is added to a spherical conductor of radius 20.0 cm.
(a) If the maximum electrical field the air surrounding
the sphere can sustain without the molecules being ionized is 3.00
× 106 V/m, what is the maximum charge that can be placed
on the sphere?
Let the charge placed on the sphere be 5.00 μC.
(b) What is the potential at the surface of the
sphere?
(c) What is the potential at a point located 10.0 cm
from the...
An electrical conductor has a net charge h. Explain that the
electric field inside conductors equals zero in the electrostatic
case and show that the charge is distributed on the conductor
surface.
