STATEMENT - 1 If a proton and an ( )-particle enter a uniform magnetic field perpendicularly with the same speed, the time period of revolution of ( - ) 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 particles and inversely proportional to charge of particle.

Options

  1. AStatement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.
