Physics

Consider three point charges at the corners of an equilateraltriangle, its base sitting on the x-axis, with charge qA positionedat the origin, qB is at x=+3.50 cm, and qC is at the (top) thirdcorner. qC = +2.60 μC, and the net electric force on qC is 375.0 Nin the negative y direction. a. Explain briefly but clearly how youknow that qA and qB must have the same magnitude charge and whatthe sign of that charge must be. b. Find the sign and magnitude ofthe charges on qA and qB.
