An α-particle has a charge of +2e and a mass of 6.64 × 10-27 kg. It is accelerated from rest through a potential difference that has a value of 1.81 × 106 V and then enters a uniform magnetic field whose magnitude is 2.63 T. The α-particle moves perpendicular to the magnetic field at all times. What is (a) the speed of the α-particle, (b) the magnitude of the magnetic force on it, and (c) the radius of its circular path?
To calculate the velocity of the alpha particle, we have to use the law of conservation of energy.As the initial velocity of the alpha particle is zero, then we can find the final velocity,
The force on that particle,
The radius of the circular path,
