Explanation / Answer

1] We know that, T = 2pi r / v and v = qrB/m

T = 2 pi r m/qrB = 2pi m/qB= 2pi*6.65e-27/[3.2e-19*0.8] =  1.63*10^-7 s answer

2] v = qrB/m = [3.2e-19*0.4*0.8]/6.65e-27 = 15398496 m/s

3] KE = 0.5mv^2 = 0.5*6.65e-27*15398496 ^2 = 7.8840298e-13 J = 7.8840298e-13/1.6e-13 MeV

= 4.93 MeV answer
