A uniform magnetic field B into the plane is present in the region enclosed by a circle of radius R.A particle of charge 'q' and mass 'm' enters normally into this region with speed v as shown. It comes out normally after time T as shown in figure. Initial and final velocities are along radial direction and they are perpendicular to each other. For this to happen. If `T=(pi R)/(nv)` find n.(Neglect gravity)

A particle of charge q and mass m enters normally (at point P) in a region of magnetic field with speed v. It comes out noramally from Q after time T as shown in Fig. The magnetic field B is present only in the region of radius R and is uniform.
