Question

If the work is to be done to take $5C$ electric charge from one point to another point is $20J$, what will be the potential difference between these two points ?

• A. $3V$
• B. $15V$
• C. $5V$
• D. $4V$

Answer 1

The correct option is D $4V$

$Q=5C$

another point $=20J$

work done $=qV$

or, $20=5\times V$

or, $V=\frac{20}{5}=4V$
