Three positive charges are fixed in place. Q 1= +4.0 nC and is located at (0,2), Q2= +1.0 nC and is located at (0,-1) and Q3= +2.0 nC and is located at (-3,0). The ruling on the axis correspond to 10.0 cm. What is the y-component or the electric field at the origin? What is the x-component of the x-component of the electric field at the origin? What is the electric potential at the origin?
