Charges q,q,and -q are placed on the x-axis at x = 0,x = 2 m,and x = 4 m,respectively.At which of the following points does the electric field have the greatest magnitude?

Question

Quizplus · Accepted Answer

The electric field due to the charge configuration will be maximum at a point where the distances to the positive and negative charges are equal. This means that the electric field will be maximum at x = 3 m, where the distance to the positive charge at x = 2 m and the negative charge at x = 4 m are equal. Therefore, the answer is choice B, x = 3 m.
