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
A. `(pi)/(100)m`
B. `(pi)/(125)m`
C. `(pi)/(250)m`
D. `(pi)/(215)m`
