A point charge q1 = 5.00nC is placed at x = 4.00cm, and a second point charge q2 = -3.00 nC is placed at x= 6.00 cm.
a) What is the magnitude and direction of the electric field due to the charges, at the origin x = 0cm?
b) What is the magnitude of the electrical potential at the origin?
c) What would be the magnitude and the direction of the electric force on a Q = 8.0nC charged particle subsequently place at the origin?
d) How much work would be required to place Q ate the origin? Assume that the electric potential at infinity is 0.
