Assume the charge distribution in the figure. Where q1=-86 Uc, q2=50Uc, q3=65Uc a) Calculate the force vector on q3 due to q1 and q2, calculating the x and y components in the axis system defined in the figure b) What is the magnitude of the net force on q3 c) What is the angle of the net force vector with the x axis? d) If we wanted the net force to be zero by placing an additional charge q4, where would we place it? 93 0.6m 0.3m 92 30 91 0.52m k
