Calculate the electrostatic force exerted on the point charge by the cylinder and what level of uncertainty would be acceptable in the initial position? You may assume that the uncertainty in all other parameters is negligible
Perpetual motion machines have fascinated people especially inventors for hundreds of years before the laws of thermodynamics became known. Ideally, once energy is added to start a perpetual motion in machine, the machine would continue to operate..
