Question

What potential difference vwc between the wire and the cylinder produces an electric field of 2.00Ã104 volts per meter at a distance of 1.20 centimeters from the axis of the wire? (assume that the wire and cylinder are both very long in comparison to their radii.)?

Answer 1

The potential difference Vwc between the wire and the cylinder produces an electric field of 2.00Ã104 volts per meter at a distance of 1.20 centimeters from the axis of the wire is 1160 VIn case of a long wire, electric field E is inversely proportional to r Therefore E= x/r or x = E*rNow,
