In Problems 63 through 66 you are given the equation(s) used to solve a problem. For each of these
a. Write a realistic problem for which this is the correct equation(s).
b. Finish the solution of the problem
An infinite plane of charge with surface charge density has a -diameter circular hole cut out of it. What is the electric field strength directly over the center of the hole at a distance of ?
Hint: Can you create this charge distribution as a superposition of charge distributions for which you know the electric field?
A small object is released at point in the center of the capacitor in FIGURE . For each situation, does the object move to the right, to the left, or remain in place? If it moves, does it accelerate or move at constant speed?
a. A positive object is released from rest.
b. A neutral but polarizable object is released from rest.
c. A negative object is released from rest.
Rank in order, from largest to smallest, the electric field strengths to at the five points inFIGURE . Explain.
