Try to have the equipotential lines equally spaced in voltage. Then, use an E-Field Sensor to measure the electric field at a few points while looking at the relationship between the electric field and the equipotential lines.
Which of the following statements is true?

1.The electric field strength is greatest where the voltage is the smallest.
2.The electric field strength is greatest where the equipotential lines are very close to each other.
3.The electric field strength is greatest where the voltage is the greatest.

2 The electric field strength is greatest where the equipotential lines are very close to each other.

Explanation:

Equipotential lines are  contour lines which trace the lines of identical altitudes. In physics, they trace out lines of equal electric potential or voltage.

Equipotential lines are always perpendicular to the electric field. The closer the equipotential lines to each other, the greater the strength of the electric field.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
