Unformatted text preview: x = 0 on the x-axis. (a) ±ind the work done in moving a second electron along the x-axis From the point x = 10 to the point x = 1. (b) ±ind the work done in moving the second electron along the x-axis From the point x = M to the point x = 1. (c) What happens to your answer in b) (which should depend on M ) as M → + ∞ ? 3. Compute the work necessary to raise a triangular sail 13 feet wide, 20 feet high, and 75 lb of weight from the boom (horizontal pole) to its maximum extent (20 feet high). 4. Water is pumped into a spherical tank of radius 5 ft from a source located 2 ft below a hole at the bottom (Fgure to the right). The density of water is 62.4 lb/ft 3 . a) Calculate the work required to Fll the tank. b) Calculate the work F ( h ) required to Fll the tank to a height h ft from the bottom of the sphere. c) Graph the function F ( h ) for 0 ≤ h ≤ 10.
