TWO EASY PHYSICS QUESTIONS
The figure below shows equipotential lines in a region of space. The equipotential lines are spaced by the same difference in potential, and several of the potentials are given. Between each pair of points, which of have the greatest electric field? pair will y (m) 1.0 100 V 0.5 0 V 0.5 -300 V 1.0 T x (m) 0.5 1.0 0.5 1.0 Copyright 2007.

From b to a From a to c From b to c Electric field is equal between all pairs UESTION 6 5 points Save Answer What is true about the electric potential and field inside of the car? The potential is the same throughout the car and the electric field is zero. O The potential is zero throughout the car and the electric field is greater than outside of the car. Both the electric field and the potential decrease from the center of the car to the edge of the car O The potential is zero throughout the car and the electric field is equal than outside of the car.Explanation / Answer
From the given figure the electric potential lines are spaced by some potential difference. The magnitude of electric field is given by density of potential lines. Thus, the potential lines are more in between the point b and point c. Therefore, the magnitude of electric field is greatest from b to c.
The car is like a conductor and the charge distributed over the surface of the car. Thus, the electric field inside a conductor is zero. The electric potential remains same throughout the car. In which is behaves like an equipotential surface.
Therefore, the option: The potential is the same throughout the car and the electric field is zero.
