P16.2) Refer to the drawing on the right. Suppose q = +1 C and q = +2 C. a) Find all points along the x axis (y=0) where the electric field is zero. 91 92 X b) Are there any points above or below the x axis where the electric field is zero? Explain. x = 0 x = 5 m P16.3) Refer to the drawing for P16.2. Suppose q = +2 C and q = -1 C. Find all points along the x axis (y=0) where the electric field is zero.
