(Figure 3.27) shows equipotential surfaces. What is the direction of electric field `vec E` at P and R?
.

Options

A. At P, electric field E is to the left and at R is upward.
B. At P, electric field E is to the Right and at R is upward.
C. At P, electric field E is to the left and at R is downward.
D. None of the Above

Answer

A

Explanation

Electric field lines are perpendicular to the equipotential surfaces and point in the direction of decreasing potential. At P, electric field `vec E` is to the left and at R, `vec E` is upward.
