Electric Potential & Equipotentials

Following figure indicates the electric potential V as a function through 4 regions on x-axis. Which of the following is correct for the electric field E in these regions?

Show answer and solution

Answer: (c)

$E = -\frac{dV}{dx}$ : magnitude of $E$ equals the slope of the $V$ – $x$ graph.
Regions 1 (AB) and 3 (CD) are flat: $E_1 = E_3 = 0$ .
Region 4 (DE) is much steeper than region 2 (BC), so $E_2 < E_4$ .
So the answer is (c) $E_1 = E_3$ and $E_2 < E_4$ .
