Electrostatic Potential and Capacitance

Question:

Two points charges q1 = +1 µC and q2 = – 2 µC are placed at A and B respectively as shown in the figure. The distance between q1 and q2 is 4 cm.

The electrostatic potential is zero on line AB at

Options:

a point on the line AB between q1 and q2 but closer to q1

a point on the line AB but not between A and B

infinitely many point in space

no point in space

Correct Answer:

a point on the line AB between q1 and q2 but closer to q1

Explanation:

The potential is zero at a point between the charges where distance is large from $2\mu C$
