# The electric potential along the x-axis is , where is in meters. What is at (a) and (b) ?

See the step by step solution

## Step 1 : Given information and theory used

Given : The electric potential along the x-axis is :

(a) and (b)

Theory used :

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

## Step 2 : Calculating

The negative derivative of the potential is equivalent to the component of the electric field. As a result,

(a) We have .
