Created by StemPy LabTwo small identical balls hang from one point on threads of equal length. Each carries the same charge, and the balls hang a small distance apart. If the charge of each ball is doubled, by what factor does grow? Assume the angles stay small.

← A +36 µC charge and a +4 µC charge are fixed on a line, 120 cm apart. A small positive charge between them feels no net force. How far is it from the +36 µC charge?In air, a charge of +32 nC and a charge of -2.0 nC are fixed 0.42 m apart. Find the point on the line joining them, outside the pair, where the electric field is zero. How far is it from the -2.0 nC charge? →
