A charged sphere of mass m and charge q starts sliding from rest on a vertical fixed circular track of radius R from the position as shown in figure. There exists a uniform and constant horizontal magnetic field of induction B

A magnetic field has a magnitude of 1.5 * 10^-3 T and an electric field 6 m/s as a magnitude of 4.0 * 10^3 N/c. Both fields point in the same direction. A positive 1.8 muC charge moves at a speed of 2.0 * 10 ^6 m/s
