  1. If I bring a charged rod to a leaf electrometer:A] nothing will happenB] nothing will happen until I touch the electrometer with the rod - then the leaves will spread apartC] the leaves will spread apart when I get the rod close to the electrometer

  2. What is the direction of the electric force on a negative charge at 1? Ans:leftA] to the rightB] to the leftC] upD] down What is the direction of the electric force on a positive charge at 2?Ans: left

  3. If I put a + charge at 3., what is the direction of the electric force?Ans: CA] straight down, directly toward the - chargeB] straight up,directly away from the - chargeC] a little to the right from straight downD] a little to the left from straight down

  4. What could be the charges here?Assume that all field lines are shown. Ans: BA] Q1 = +3C, Q2 = -2 CB] Q1 = +18C, Q2= -10 CC] Q1= -18C, Q2=+10 CD] Q1 = +9 C, Q2 = +5 CE] none of these
