Fe Fe d W Given Data: Mass of each aluminum ball: 0.048 +/- 0.01 g Length of string from suspension point to aluminum balls: 13.5 +/- 0.1 cm The angles below are measured from the vertical line to one suspended aluminum ball. g.pail per ball is half the reading of the charge sensor when both aluminum balls were lowered into the pail: Trial 1: angle=8+/-1deg, gRail per ball=2.7+/-1nC Trial 2: angle=8+/-1deg, g.pail.per ball=2.9+/-1nC Trial 3: angle=7+/-1deg, g.Rail per ball=2.5+/-1nC Calculate the charge based on the x-component of tension being set equal to coulombs force. You are given mass of the aluminum, angle theta, length of the string, and you know acceleration due to gravity. Once you calculate the x component you can get charge q. (make sure units are SI units to get values close to the logger pro calculations).
