1. The problem statement, all variables and given/known data Four pairs of conducting spheres, all with the same radius, are shown in the figure, along with the net charge placed on them initially. The spheres in each pair are now brought into contact, allowing charge to transfer between them. Rank the pairs of spheres in order of increasing magnitude of the charge transferred. Indicate ties where appropriate. (Use only the symbols < and =, for example A < B = C.) 2. Relevant equations F=kq1q2/r2 F=q1+q2/2 3. The attempt at a solution Since I only get one chance to do this problem, I just want to make sure if my reasoning is correct or if the formula I am using correct. What i think is: A=-3C B=4C C=-2C D= 14C Increasing order: A<C<B<D OR Multplying: A= 5C B= 0 C=5C D=195C Increasing order: B<A=C<D Any insight is appreciated.
