Homework Statement
Use a Cartesian system whose origin coincides with the midpoint between the two charges and write
the expression for the magnitude of electric field [itex]\vec{E}[/itex]
on the line passing through the two charges.
Then Show that when the two charges have the same sign, there is a point X0 along the line connecting the two charges where [itex]\vec{E}[/itex] vanishes
