A particle of mass \( m \) and charge \( q \) is projected into a region having a perpendicular magnetic field \( B \). Find the angle of deviation of the particle as it comes out of the magnetic field, if the width of the region is(a) \( \frac{2 m v}{B q} \)(b) \( \frac{m v}{B q} \)(c) \( \frac{m v}{2 B q} \)
