Q. The figure gives the electric potential $V$ as a function of distance through five regions on $x$-axis. Which of the following is true for the electric field $E$ in these regions
A) $E_{1} > E_{2} > E_{3} > E_{4} > E_{5}$
B) $E_{1} = E_{3} = E_{5}$ and $E_{2} < E_{4}$
C) $E_{2} = E_{4} = E_{5}$ and $E_{1} < E_{3}$
D) $E_{1} < E_{2} < E_{3} < E_{4} < E_{5}$
Explanation
(b) Electric field in the region 1, 3 and 5 is zero
$i.e.\ E_{1} = E_{3} = E_{5}$
Slope of the line $BC <$ Slope of the line $DE$
$i.e.\ E_{2} < E_{4}$
