Explanation / Answer

The equipotentials are most closely spaced along the x-axis between x = 2 m and x = 5 m.

The potential decreases in the direction of the electric field, which, for 2 m x 5 m, is in the negative x direction.

The potential drops by 10 V/m, which is the field strength in this region.
