Coulombs Law !! Please Help 1. The problem statement, all variables and given/known data Two metal balls A and B of negligible radius are floating at rest on Space Station Freedom between two metal bulkheads, connected by a taut nonconducting thread of length 1.30 m. Ball A carries charge q, and ball B carries charge 2q. Each ball is 1.66 m away from a bulkhead. (a) If the tension in the string is 4.00 N, what is the magnitude of q? (b) What happens as time passes ? 2. Relevant equations F= Ke x q1 q2/r2 3. The attempt at a solution I know the constant for Ke = 8.9875 x 10 9 N*m2/c2 And know the distance between the two objects is held together by a string with a certain tension of 4 N. Quite honestly, I dont even know where to begin. She says this is a simple problem, but I dont feel the same way :) Any help or suggestions as to where I should start would be greatly appreciated !
