2 problems. I was just wondering if someone can help me start off the problem. The rest, I'll try to do because I don't know how to setup the problem.
55) A virus rests on the bottom plate of oppositely charged parallel plates in the vacuum chamber of an electron microscope. The electric field strength between the plates is 2.00 x 10^5 N/C and the bottom plate is negative. If the virus has a mass of 1.00 x 10^-15kg and suddenly acquires a charge of -1.60 x 10^-19C, what are its velocity and position 75.0ms later? Do not disregard gravity.
Answer: v=1.67 m/s upward
y=6.24cm above bottom plate
59) The immediate cause of many deaths in ventricular fibrillation, uncoordinated quivering of the heart as opposed to proper beating. An electric shock to the chest can cause momentary paralysis of the heart muscle after which the heart will sometimes start organized beating again. A defibrillator is a device that applies a strong electric shock to the chest over a time of a few milliseconds. The device contains a capacitor of several microfarads, charged to several thousand volts. Electrodes called paddles, about 8cm across and coated with conducting paste, are held against the chest on both sides of the heart. Their handles are insulated to prevent injury to the operator, who calls, "Clear!" and pushes a button on one paddle to discharge the capacitor through the patient's chest. Assume that an energy of 300W·s is to be delivered from a 30.0µF capacitor. To what potential difference must it be charged?
Answer: 4.47kV
