Statement 1: If a proton and an alpha -particle enter a uniform magnetic field perpendicularly with the same speed, the time period of revolution of alpha -particle is double than that of proton. Statement 2: In a magnetic field, the period of revolution of a charged particle is directly proportional to the mass of the particle and inversely proprotional to the charge of particle.
