In the coordinate system shown in the figure, particle 1 with charge q1 = 4.5 μC is located at coordinates (x1,y1) = (-3, 0) m and particle 2 with charge q2 = -11 μC is located at coordinates (x2,y2) = (1, 0) m. a. If you assume the potential vanishes at infinity, the potential will be zero at some point (x0,0) with -3 m < x0 < 1 m. Write an expression for x0 in terms of q1, q2, x1, and x2.  b. Solve for the numerical value of x0.   c.  Select the correct expression for the magnitude of electric field E0 at point (x0,0) in terms of q1, q2, x1, and x2.    d. Solve for the numerical value of E0, in newtons per coulomb.
