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.
A parallel-plate capacitor has electrodes with surface charge densities . A proton traveling parallel to the electrodes at enters the center of the gap between them. By what distance has the proton been deflected sideways when it reaches the far edge of the capacitor? Assume the field is uniform inside the capacitor and zero outside the capacitor.
What are the strength and direction of the electric field at the position indicated by the dot in FIGURESpecify the direction as an angle above or below horizontal.
Air "breaks down" when the electric field strength reaches , causing a spark. A parallel-plate capacitor is made from two electrodes. How many electrons must be transferred from one electrode to the other to create a spark between the electrodes?
