The diagram shows the electric field in the vicinity of a charge.

Question

One positive charge labeled Y. Vectors start perpendicular to the surface and spread out in all directions. Directly above is W. On the right is X and on the left is Z. The vectors are closer together below the charge and further apart above.
At which point is the electric field strongest?

W
X
Y
Z

Answer 1

The electric field produced by a point charge (like the positive charge labeled Y) is strongest in the vicinity of the charge itself and decreases with distance. The vectors representing the electric field lines spread out from the charge and are closer together near the charge, indicating a stronger electric field in that region.

Since you mentioned that the vectors are closer together below the charge and further apart above, it suggests that the electric field is strongest directly around the charge. Therefore, the electric field would be strongest at point Y, as that is where the electric field lines are most concentrated.

Thus, the answer is Y.
