Twodiameter charged rings face each other,apart. Both rings are charged to. What is the electric field strength at (a) the midpoint between the two rings and (b) the center of the left ring?
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 proton orbits a long charged wire, making revolutions per second. The radius of the orbit is . What is the wire’s linear charge density?
One type of ink-jet printer, called an electrostatic ink-jet printer, forms the letters by using deflecting electrodes to steer charged ink drops up and down vertically as the ink jet sweeps horizontally across the page. The ink jet forms diameter drops of ink, charges them by spraying electrons on the surface, and shoots them toward the page at a speed of . Along the way, the drops pass through two horizontal, parallel electrodes that are wide, and spaced apart. The distance from the center of the electrodes to the paper is . To form the tallest letters, which have a height of , the drops need to be deflected upward (or downward) by . What electric field strength is needed between the electrodes to achieve this deflection? Ink, which consists of dye particles suspended in alcohol, has a density of .
