a) Using work done through the potential difference is W = change in kinetic energy
q*V = 0.5*m*v^2
2*1.6*10^-19*1.42*10^6 = 0.5*6.64*10^-27*v^2
v = 1.16*10^7 m/s is the answer for a)
b) force on it is F = q*v*B = 2*1.6*10^-19*1.16*10^7*2.78 = 1.03*10^-11 N
c) radius is r = (m*v)/(q*B) = (6.64*10^-27*1.16*10^7)/(2*1.6*10^-19*2.78)
r = 0.0865 m = 8.65 cm
