Electric Potential Assignment is due at 2:00am on Wednesday, February 7, 2007 Credit for problems submitted late will decrease to 0% after the deadline has passed. The wrong answer penalty is 2% per part. Multiple choice questions are penalized as described in the online help. The unopened hint bonus is 2% per part. You are allowed 4 attempts per answer. Potential of Conductors that Touch and Separate Conducting Tetrahedra Two conductors, A and B, are each in the shape of a tetrahedron, but of different sizes. They are charged in the following manner: Tetrahedron A is charged from an electrostatic generator to charge . 1. Tetrahedron A is briefly touched to tetrahedron B. 2. Steps 1 and 2 are repeated until the charge on tetrahedron B reaches a maximum value. 3. Part A If the charge on tetrahedron B was after the first time it touched tetrahedron A, what is the final charge on tetrahdedron B? Hint A.1 How to approach the problem Hint not displayed Part A.2 Find the ratio of the conductors' charges Part not displayed Part A.3 Find the maximum charge on A Part not displayed Express your answer in terms of . ANSWER: = Answer not displayed Charged Mercury Droplets A uniformly charged spherical droplet of mercury with electric potential breaks into identical spherical droplets, each with electric potential . The small droplets are far enough apart form one another that they do not interact significantly. Part A Find , the ratio of , the electric potential of the initial drop, to , the electric potential of one of the smaller drops. Hint A.1 How to approach the problem Hint not displayed Part A.2 Find the charge on the small droplets Keeping conservation of charge in mind, find the charge on each small droplet. Express your answer in terms of , the charge on the big droplet, and . ANSWER: = Part A.3 Find the radius of a small droplet What is the radius of each small droplet? Hint A.3.a Consider volume [
