What is the work done to flow a charge of 5C between two points having a potential difference of 15 V?

Answer: Option C

Explanation:
The work done to move a charge between two points is related to the potential difference between those points.
We can use the formula: Work Done (W) = Charge (Q) x Potential Difference (V)
In this case, the charge (Q) is 5 Coulombs (C) and the potential difference (V) is 15 Volts (V).
So, W = 5 C x 15 V = 75 Joules (J)
Therefore, the correct answer is Option C: 75 J.
