A charged particle (q.m) released from origin with velocity `v=v_(0)hati` in a uniform magnetic field `B=(B_(0))/(2)hati+(sqrt3B_(0))/(2)hatJ`.
Pitch of the helical path described by the particle is
A. `(2pimv_(0))/(B_(0)q)`
B. `(sqrt3pimv_(0))/(2B_(0)q)`
C. `(pimv_(0))/(B_(0)q)`
D. `(2sqrt3pimv_(0))/(B_(0)q)`
