1. The problem statement, all variables and given/known data On a long friction-less non-conducting straight needle are threaded an infinitely large number of identical beads.The beads are made of insulating materials and have charges of equal magnitude and alternate plus and minus signs.Assume charge distribution on a bead unaffected by other charges in its vicinity. If the first bead is pulled out with a gradually increasing force, where will the chain break first? 2. The attempt at a solution I have thought of making a variable function of Tension on the string and then differentiate it for the max value to get the position.but I have no idea about how I am going to make the equation.
