Question 1 Report

If \(8 \times 10^{-2}\,\mathrm{J}\) of work is required to move \(100\,\mu\mathrm{C}\) of charge from a point X to a point Y in an electrical circuit, the potential difference between X and Y is

Answer Details
The potential difference between X and Y in an electrical circuit is given by the equation: V = W/Q where V is the potential difference, W is the work done, and Q is the charge. From the question, we know that W = 8 x 10^-2 J and Q = 100 x 10^-6 C. Substituting these values into the equation, we have: V = (8 x 10^-2)/(100 x 10^-6) = 8 x 10^2 V Therefore, the potential difference between X and Y in the electrical circuit is 8.0 x 10^2 V. Option C is the correct answer.
