Q. A rock with mass = 2.00 falls from rest in a viscous medium. The rock is acted on by a net constant downward force of = 15.8 (a combination of gravity and the buoyant force exerted by the medium) and by a fluid resistance force , where is the speed in and = 2.44 . Find the initial acceleration.

Q. A friend is working on a biology experiment and needs to create an electric field of magnitude 460 {rm N/C} at a distance of 10 {rm cm} from the central portion of a large nonconducting square plate 5.2 {rm m} on each side. She needs to know how much charge to put on the plate. What do you tell her?
