A particle of charge q and mass m is projected with a velocity `v_0` toward a circular region having uniform magnetic field B perpendicular and into the plane of paper from point P as shown in Fig. 1.136. R is the radius and O is the center of the circular region. If the line OP makes an angle `theta` with the direction of `v_0` then the value of `v_0` so that particle passes through O is
