Three point charges are arranged along the x axis. Charge q1 = -4.70 nC is located at x= 0.230 mand charge q2 = 2.60 nC is at x= -0.320 m . A positive point charge q3 is located at the origin.
Part A:What must the value of q3 be for the net force on this point charge to have magnitude 3.00 μN ?
Part B:Where along the x axis can q3 be placed and the net force on it be zero, other than the trivial answers of x=+∞ and x=−∞?
