The dielectric strength of air e 30 x 106 vm is the

Question

Solve the all parts of given question:

Question: The dielectric strength of air, E = 3.0 x 10⁶ V/m, is the maximum field that air can withstand before it breaks down and becomes conducting.

Part A: How much charge can be placed on a spherical conductor with an 11.0- cm radius before the field at its surface exceeds the breakdown strength of the air?

Part B: What would be the electric potential at the surface of this conductor?

Don't just give me the answer; explain your steps as well.
