Reference no: EM13560503

Charges of -q and +2q are fixed in place, with a distance of 2.00mbetween them. A dashed line is drawn through the negative charge, perpendicular to the line between the charges. On the dashed line,at a distance L from the negative charge, there is at least one spot where the total potential is zero. Find L.
