Problem 4
(a) An irregular shaped hollow conductor has excess negative charge on it. (The
figure right shows the cross-sectional view of the conductor.) It is found that this
conductor has electric potential of $-3.2 \text{V}$ at its outer surface.
1. Using arrows, indicate the direction of the electric field at locations 1, 2, 3,
and 4 (Example: ). If there is no field, write \text{``zero''} next to the dot.
2. Order the location numbers (1, 2, 3, and 4) in an order of increasing electric field strength: $4, 2, 1, 3$
3. What is the electric field (E) in the hollow region.
$E = 0 \frac{V}{m}$
4. What is the voltage (V) inside the conductor?
$V = -3.2 \text{V}$
