305: An electron is directly west of a proton. The force on the electron is in what direction: north, south, east, or west?
ANSWER: EAST or TOWARD THE PROTON
306: At a point halfway between two identical point charges, the electric field is equal to:
w) Zero
x) Half its maximum value
y) Its maximum value
z) Pointing away from the two charges
ANSWER: W -- ZERO
307: Ten coulombs of positive charge are placed on an irregularly-shaped, solid piece of copper. Once the charge has stopped moving, the electric field inside the copper is:
w) Zero
x) Changes as one over the radius squared
y) Becomes smaller as you approach the center
z) becomes larger as you approach the center
ANSWER: W -- ZERO
308: Ten coulombs of charge are placed on a solid copper sphere. Once the charge has come to rest, the ELECTRIC POTENTIAL inside the sphere is found to be:
w) Zero
x) Uniform inside the sphere and equal to the electric potential on the surface of the sphere
y) Smaller than the electric potential outside the sphere
z) Varying as one over r squared
ANSWER: X -- UNIFORM INSIDE THE SPHERE AND EQUAL TO THE LECTRIC POTENTIAL ON THE SURFACE OF THE SPHERE
