Question

Four point charge of magnitude 1μC each are located at the four corners of square.Calculate the force on a 3μC charge placed at the centre of the square?

Answer 1

This is your answer and hope it helps

Answer 2

Answer:

ZERO

Explanation:

Four charges of magnitude 1μC are located at four corners of a square.

Four corners are equidistant from centre of the square.

So no matter what charge you place at centre it experiences no force.

This is because, think of a ball tied to four ropes, such that each rope is perpendicular to its adjacent ropes. Let this ropes are being pulled by four persons who are applying equal strengths. Will the ball move? Obviously not!

Similarly in this case the 3μC charge will not be facing any net force.
