Electrostatic Potential and Capacitance

Question:

Two point changes -q and +q are located at points (0, 0, -a) and (0, 0, +a) respectively. The electric potential of a point (0, b, 0), where b > a, is:

Options:

Zero

$\frac{1}{4 \pi \epsilon_{o}} \frac{q}{b^2}$

$\frac{1}{4 \pi \epsilon_{o}} \frac{2 qa}{\left(b^2-a^2\right)}$

$\frac{1}{4 \pi \epsilon_{o}} \frac{2 qa}{\left(b^2+a^2\right)}$

Correct Answer:

Zero

Explanation:

The correct answer is Option (1) → Zero
