Electrostatic Potential and Capacitance

Question:

Assume that an electric field $(20x^4\hat i)Vm^{-1}$ exists in the region of space. If $V_0$ is the potential at the origin and $V_A$ is the potential at x = 1 m., then the potential difference $V_A-V_0$ is:

Options:

-20 V

+2 V

-4 V

+4 V

Correct Answer:

-4 V

Explanation:

The correct answer is Option (3) → -4 V
