Examination of the coulombs forces on charged beads

The acclerations of two charged beads one a charged plastic bead of mass 2.4g, charge -3.0 nC the other a glass bead of mass 4.5g charge 18.5 nC separated a centre to centre distance of 2.3 cm are determined

First of all I have drawn a schematic showing the two beads ( & charges ) separated by a distance R = 2.3 cm. I have given the plastic bead the suffix 1 and the glass bead the suffix 2 in the formulation of any equations. All units specified in the question have been translated to SI units so charges are specified as inputs to the equations that follow in units of Coulombs, masses are in units of kg, distances are in units of metres.

Taking the positive x direction for +ve force

The force experienced by the plastic bead is deduced from Coulombs Law [1] in (1) ...
