1. An electric field (in v/m) varies with postion along the yaxis according to E = 1/y. Find the electric potential differenceVAB if A is a point on the y axis at y = 5 m and B is apoint on the y axis at y = 7 ?
- VAB = 0.28 volts
- VAB = 0.34 volts
- VAB = 0.49 volts
- VAB = 0.82 volts
2. How does the electric potential at a point x, a finitedistance away from a large positive charge, compare to a point x/2from 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
3.
2. Which of the following doesn't depend upon the charge thatmoves 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
