The electric potential in a certain region of space is given by V = -7.5x² + 3x, where V is in volts and x is in meters.In this region the equipotential surfaces are:

Question

Quizplus · Accepted Answer

The electric potential V given as a function of x alone (-7.5x^2 + 3x) implies that the potential changes with x but is constant with respect to y and z. Therefore, the equipotential surfaces, which are surfaces of constant potential, must be perpendicular to the x-axis and parallel to the yz plane. This makes planes parallel to the yz plane the correct choice.
