Question

A large cylindrical metal tank of height "h" and radius "R" has a charge of "Q" put on it. A voltmeter connected at the bottom of the tank reads 1000 volts. The voltage at a point halfway up the tank (z=h/2) and halfway out towards the wall (radius r=R/2) would have a voltage of:


If none of the answers are right, select "none of these"

If none of the answers are right, select "none of these"

The reason that the voltage is 1000 volts everywhere inside the tank is,

The reason that the voltage is 1000 volts everywhere inside the tank is,

Q??0R None of these
Q4??0r
Q2??0hLn(rR)

Explanation / Answer

None of these


Electric Field is zero inside a closed conductor (with no charge inside the tank)
