What will be the nature of the path of a charged particle when it enters a uniform magnetic field vec(B) normally?

A charged particle moving along +ve x-direction with a velocity v enters a region where there is a uniform magnetic field B_0(-hat k), from x=0 to x=d. The particle gets deflected at an angle theta from its initial path. The specific charge of the particle is

A charged particle with charge to mass ratio ((q)/(m)) = (10)^(3)/(19) Ckg^(-1) enters a uniform magnetic field vec(B) = 20 hat(i) + 30 hat(j) + 50 hat(k) T at time t = 0 with velocity vec(V) = (20 hat(i) + 50 hat(j) + 30 hat(k)) m//s . Assume that magnetic field exists in large space. The pitch of the helical path of the motion of the particle will be
