Problem

The electric field in a region is given by

\vec{E} = (Ax + B)\hat{i}

, where

E

is in

\text{NC}^{-1}

and

x

is in metres. The values of constants are

A = 20\text{ SI unit}

and

B = 10\text{ SI unit}

. If the potential at

x = 1

is

V_1

and that at

x = -5

is

V_2

, then

V_1 - V_2

is : [Main 8 Jan. 2019 II] a.

b.

-48\text{ V}

c.

180\text{ V}

d.

-520\text{ V}
