Suppose 12 charged particles of identical charge q are placed around the circumference of a clock of radius r, one at each number positions uniformly separated. (a) Derive the equation for net electric force on a test charge Q placed at the center of this clock? (b) Suppose you remove the charge from 6 o\\\'clock position, what will be the new net electric force and in which direction?
