A uniform electric field given by E- (2.607-5.45) x 105 N/C permeates a region of space in which a small negatively charged sphere of mass 1.60 g is suspended b light cord (see figure below). The sphere is found to be in equilibrium when the string makes an angle = 23.0*. (a) What is the charge on the sphere? (Enter the magnitude.)
