Chapter 16 - Electric Charge and Electric Field - Questions: 16

Answer

The field is the strongest between the two charges and weakest to the left of the positive charge.

Work Step by Step

Considering only points that are 2.5 cm away from the positive charge, to the right of the positive charge (between the two charges), the electric field is strongest. The field from the positive charge points in the same direction (to the right) as the one from the negative charge, and they add to make a stronger field. Considering only points that are 2.5 cm away from the positive charge, to the left of the positive charge, the electric field is weakest. The individual fields from the positive charge and negative charge point left and right, respectively, so they partially cancel.
