Two point charges lie on the x axis. A charge of +6.37 uC is at
the origin, and a charge of -9.54 uC is at x = 12.0 cm. What is the
net electric field at x = -3.89 cm?

Two point charges lie on the x-axis. A charge of -5.5
microcoulombs is at the origin, and a charge of +4.5 microcoulombs
is at x = 10.0 cm.
a. what is the net electric field at x = -4.0 cm?
b. what is the net electric field at x = +4.0 cm?

Initially two positive charges lie on the x-axis:
qA is at the origin and qB
is at (23.8 cm,0). The electric field created by these charges is
zero at (6.13 cm,0).
Now the charge on qA is reversed (from
positive to negative). Find the x-coordinate of the point
on the x-axis where the electric field is zero now, in cm. Your
answer must include the sign of the x-coordinate.
