Question

is the potential difference between two points, when 3 J of work is done in moving 2.3 C of charge between them.

• A. $2.506\text{V}$
• B. $1.304\text{V}$
• C. $3.214\text{V}$

Answer 1

The correct option is B $1.304\text{V}$

We know, potential difference,$\text{V}$ = $\frac{\text{W}}{\text{Q}}$
where, $\text{W}$ is the amount of work done in moving the charge between two points, and $\text{Q}$ is the amount of charge moved.

Given: $\text{W}=3\text{J}$ and $\text{Q}=2.3\text{C}$
$⟹$ $\text{V}=\frac{3}{2.3}=1.304\text{V}$
