Answer 1

Answer #1

E=kq/r^2

E=kq/r^2
at r=1
E=kq=9
at r=3
E=kq/r^2=9/3^3=9/9=1V/m

The dielectric strength of air, E = 3.0×106 V/m, is the maximum field that air can withstand before it breaks down and becomes conducting. How much charge can be placed on a spherical conductor with a 8.0- cm radius before the field at its surface exceeds the breakdown strength of the air? The answer to this section is 2.14×10-6 C. My question: What would be the electric potential at the surface of this conductor?
