Q. An electric field of 2.60 × 105 V/m is desired between two parallel plates each of area 23.0 cm2 and separated by 0.250 cm of air. What charge must be on each plate?

Q. The great, gray-green, greasy Zambezi River flows over Victoria Falls in south central Africa. The falls are approximately 108 m high. If the river is flowing horizontally at 3.60 m/s just before going over the falls, what is the speed of the water when it hits the bottom? Assume the water is in freefall as it drops.
