Chapter 26: Q. 13 (page 738)

The electric potential in a region of uniform electric field is $- 1000 V$ at $x = - 1.0 m$ and $+ 1000 V at x = + 1.0 m$ . What is $E_{x}$ ?

Short Answer

Expert verified

$E_{x} = - 1000 V / m$

Step by step solution

Given information and theory used

Given :

The electric potential is : $- 1000 V at x = - 1.0 m$ and

$+ 1000 V at x = + 1.0 m .$

Theory used :

The electric field is expressed as a function of potential as :

E (x) = - \frac{d V (x)}{d x}

Calculating Ex

In a given region, the uniform electric field is equal to minus the difference in potential divided by distance.

So,

$E_{x} = - \frac{1000 V - (- 1000 V)}{1 m - (- 1 m)} = - 1000 V / m$ is the result.
