Two identical small insulating balls are suspended by separate 0.26-m threads that are attached to a common point on the ceiling. each ball has a mass of 7.75 10^-4 kg. initially the balls are uncharged and hang straight down. they are then given identical positive charges and, as a result, spread apart with an angle of 35° between the threads. (a) determine the charge on each ball. (answer in c)

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle can be assumed at 30 deg
