A small glass bead charged to 4.5 nC is in the plane that bisects a thin, uniformly charged, 10-cm-long glass rod and is 4.0 cm from the rod's center. The bead is repelled from the rod with a force of 940 μN.
What is the total charge on the rod?
q = bead
Q = rod
the electric field at the glass bead pocation is
(Gauss’ theorem)
E = Q / (2 π d L εo)
the force is
F = q E = q Q / (2 π d L εo)
then
Q = 2 π d L εo F / q
Q = 2*3.14*4x10^-2*10^-1*8.85x10^-12*940x10^-6 / 4.5x10^-9 = 4.65x10^-8 C = 46.5 nC
