Two equal and opposite charges of magnitude 2.00µC and -2.00µC are held .15 m apart.
A. What is the magnitude and direction of the electric field at a point midway between the charges?
B. What force (magnitude & direction) would act on an electron placed at the midway point?
C. If the -2.00µC is replaced with a +3.00µC at what location would the electric field sum to zero between the two positive charges (Hint: Use the Quadratic formula)
