Question

An electric charge of 20 mC is situated at the origin of X-Y co-ordinate system. The potential difference between the points. (5a, 0) and (- 3a, 4a) will be

• A. a
• B. 2
• C. Zero
• D. $\frac{a}{\sqrt{2}}$

Answer 1

Answer: (C)

Zero

Answer 2

$V_{A} = \frac{kQ}{5a}$ and $V_{B} = \frac{kQ}{5a}$

\f0 $V_{A} - V_{B} = 0$
