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 `E` in these regions ?

Options

A. `E_(2) = E_(4),E_(5) = 0 and E_(3) gt E_(1)`
B. `E_(1) = E_(3),E_(5) = 0 and E_(2) lt E_(4)`
C. `E_(2) = E_(4),E_(5) = 0 and E_(1) lt E_(3)`
D. `E_(1) lt E_(2) lt E_(3) lt E_(4) lt E_(5)`

Answer

B

Explanation

Electric field in the region `1, 3` and `5` is zero i.e.,
`E_(1) = E_(3) = E_(5)`
Slope of the line `BC lt` Slope of the line `dE`
i.e., `E_(2) lt E_(4)`
