Question

The electric potential in a region of uniform electric field is -1600 V at x = -1.30 m and + 2000 V at x =+ 1.80 m . What is Ex? Express your answer with the appropriate units.

Answer 1

Answer:

-1161.29 V/m

Explanation:

The x component of electric field will be given by

$E_x= -\frac {\triangle V}{\triangle x}$

Here $\triangle V$ is the change in voltage while triangle x is the change in x

$E_x= -\frac {+2000 V--1600V}{\triangle 1.8--1.3}=-\frac {3600}{3.1}=-1161.29 V/m$
