Question

Calculate the amount of work done in moving a charged particle of charge $q$ through a potential difference of $V$.

• A. $\frac{q}{V}$
• B. $\frac{V}{q}$
• C. $\frac{1}{qV}$
• D. $qV$

Answer 1

The correct option is D $qV$

Potential difference is defined as the work done to move per unit positive charge from one point to another.

Let us say that a charge $q$ is moving from one place to another place under the potential difference $V$.

$V=\frac{W}{q}$

$⟹W=qV$

Answer-(D)
