    If there are two point charges on an x-axis. Q1=2.9 uC and Q2=-1.7uC. Q2 is placed at the origin, and Q1 is placed at the coordinate x1= -4.0cm. a.) At what point along the x-axis is the electric field zero? provide the x-coordinates I got stuck at the equation: 1.7(x+0.04)^2=2.9x^2 (I don't even know if that's correct) b.) At what point along the x axis is the potential zero? Provide the x-coordinates of the points. Please Help Thank you!
