PH 2223 01 Test II-B March 4, 2003 Name:_________________________________________________Column:______________ Darken the [ ± ] of the letter of the correct answer. For possible partial credit, on your scratch paper number and show your solutions clearly. Staple your scratch paper to this test. eo e = 1.602×10 C m = 9.109×10 kg , = 8.854×10 C /Nm - 19 - 31 - 12 2 2 1. Suppose you have a uniform electric field E = 20 N/m i . If a negative charge moves in the - x direction, does its electric potential energy increase or decrease? (Caution: note the word energy.) [a] increase [b] decrease [c] no change [d] It depends on how fast it moves. 2. Keep the same electric field as in the previous question. If a positive charge moves in the - y direction, does its electric potential energy increase or decrease? [a] increase [b] decrease [c] no change [d] It depends on how fast it moves. 3. Consider a hollow spherical conductor that has a potential of 300 volts at its outside surface. The potential inside the hollow must be [a] 0 at the center and rising to something less than 300 v at the
