A particle of mass m and charge q is projected with a velocity vo in a viscous medium, where a uniform and constant magnetic field of induction B exists everywhere in a direction perpendicular to the direction of projection of the particle. The force of viscous drag on the particle is given by the law f = -bv, where b is a positive constant and v is velocity of the particle. Find distance travelled by the particle during a time interval from the instant of projection until velocity vector turns by 2pi radians.
