1. An electric field (in v/m) varies with postion along the y axis according to E = 1/y. Find the electric potential difference V_AB if A is a point on the y axis at y = 5 m and B is a point on the y axis at y = 7 ?

V_AB = 0.28 volts
V_AB = 0.34 volts
V_AB = 0.49 volts
V_AB = 0.82 volts

2. How does the electric potential at a point x, a finite distance away from a large positive charge, compare to a point x/2 from the charge?

The potential is half as big
The potential is twice as big
It depends upon the amount of charge
It depends upon the magnitude of x

2. Which of the following doesn't depend upon the charge that moves from one point in an electric field to another?

The change in electric potential energy
The work done by the E-field
The change in electric potential
The change in kinetic energy
