Two point charges are placed on the x axis.The first charge, q1=
8.00 nC, is placed a distance 16.0 m from the origin along the
positive x axis; the second charge, q2 = 6.00 nC, is placed a
distance 9.00 m from the origin along the negative x axis.
(figure provided in the solution)
Part A: Find the electric field at the origin, point O.
Part B: Now, assume that charge q2 is negative; q2 = -6 nC . What
is the net electric field at the origin, point O?
Give the x and y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant figures. Keep in mind that an x component that points to the right is positive and a
y component that points upward is positive.
