Three particles are placed in a line. The left particle has a charge of -67 X 10^-6 C, the middle, 45 X 10^-6 C, and the right -83 X 10^-6C. The middle particle is 72cm from each of the others.
a) Find the net force on the middle particle.
b) Find the net force on the right particle.

Please refer attachment.

As per Coulomb's law electrostatic force acting between two charges q1 & q2 separated by a distance r is given by :

F = (1/4Πε0) q1q2/r2 = (9x109) q1q2/r2 where ε0 is the permittivity of vacuum (or air)

If a charge is subjected to forces by ...

Solution Summary

Three charged particles for lines in place are determined. The net force on the right particles are given.
