Charge is added to a spherical conductor of radius 20.0 cm.
(a) If the maximum electrical field the air surroundingthe sphere can sustain without the molecules being ionized is 3.00× 106 V/m, what is the maximum charge that can be placedon the sphere?
Let the charge placed on the sphere be 5.00 μC.
(b) What is the potential at the surface of thesphere?
(c) What is the potential at a point located 10.0 cmfrom the center of the sphere?
(d) What is the potential at a point located outside thesphere at a distance of 5.00 cm from the surface of thesphere?
