Three equal, opposite charges are fixed at a distance d. Positive charge is at the right and negative at the left position. As shown below:+ X, - Y, + Z At which position, the net electric field is directed to the left?
Correct answer: D. Y only
- A. X, Y and Z
- B. X only
- C. X and Z only
- D. Y only
Explanation
The field is formed between the 2 charges which is from +ve charge to the -ve charge so there's no way any electric field will be on X or Z so the only place the field lines will cross is Y.

The more specific you are, the faster it gets fixed. A source beats an opinion.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
