Problem
Two point charges of +10μC and +40μC are placed 0.20m apart in air along a straight line.
Calculate the position(s) along the line (measured from the +10μC charge) where an electron would experience zero net electrostatic force. State clearly whether each position lies between the charges or outside the segment joining them.
