A uniform electric field having a magnitude E0 and direction along positive x-axis exists. If the electric potential (V) is zero at x = 0 then its value at x = + x will be-

A

Vx = xE0

B

Vx = – xE0

C

Vx = x2E0

D

Vx = – x2E0

Answer

Vx = – xE0

Explanation

Solution

E\overrightarrow { \mathrm { E } } = E0 0vxdV\int _ { 0 } ^ { v _ { \mathrm { x } } } \mathrm { dV } = – Ž Vx = – xE0
