MasteringPhysics: Assignment Print View Problem 29.8 Three electrons form an equilateral triangle 1.50 on each side. A proton is at the center of the triangle. Part A What is the potential energy of this group of charges? ANSWER: - 3.37×10 - 19 J Problem 29.25 A 2.40 -diameter glass bead is positively charged. The potential difference between a point 2.40 from the bead and a point 3.60 from the bead is 490 . Part A What is the charge on the bead? ANSWER: 7.84×10 - 10 C Potential of a Charged Cylinder A hollow cylinder of radius and height has a total charge uniformly distributed over its surface. The axis of the cylinder coincides with the z axis, and the cylinder is centered at the origin, as shown in the figure.
