question 2

Multiple Choice

Alpha particles,each having a charge of +2e and a mass of 6.64 ×10^-27 kg,are accelerated in a uniform $0.50 \mathrm {~T}$ $\vec { B }$ field to a final orbit radius of $0.50 \mathrm {~m}$ The $\vec { B }$ field is perpendicular to the velocity of the particles.What is the kinetic energy of an alpha particle in the final orbit?
