A particle with a mass of 2.00 x 10^-16 kg and a charge of 30.0 nC starts from rest, is accelerated with a strong electric field, and is fired from a small source inside a region of uniform constant magnetic field 0.600 T. The velocity of the particle is perpendicular to the field. The circular orbit of the particle encloses a magnetic flux of 15 micro(x10^-6)Wb. (a) Compute the speed of the particle and (b) Compute the potential difference during which the particle accelerated inside the source.
