A small particle of mass 1 kg and charge 1 C enters perpendicularly in a triangular region of a uniform magnetic field of strength 2 T as shown in the figure. What is the maximum velocity (in m s - 1 ) of the particle with which it can enter so that it completes a half-circle in the region of the magnetic field?
