A metal cylinder with a radius "R" is placed with its central axis aligned with the z axis. A current, I, flows along its surface only (no current flows on the interior of the cylinder). Calculate the magnetic field strength as a function of distance, r, away from the center of the cylinder for two different regions: (a) r<R and (b) r>R.
A particle having mass m = 2.80E-4 kg carries a negative charge q= −1.70E-6 C . The particle is given an initial velocity in the −y direction (downward), as shown in the figure, of v = 3.65E2 m/s. Everywhere in space there is a uniform constant magnetic field B = 0.340 T pointing in the +z direction, which is out of the plane of the page. What is the radius of the cyclotron orbit trajectory that this particle will move along (in m)?
