A charged particle P leaves the origin with speed v=v0 at some inclination with the x−axis. There is a uniform magnetic field B along the x−axis. P strikes a fixed target T on the x−axis for a minimum value of B=B0. If the pitch of the helical path is equal to the maximum distance of the particle from the x-axis, then which of the following are not correct?

Correct options are A) , B) and C)
Time period of one revolution =qB2πm
Radius of the circle r=qBmvsinθ
Max distance of the particle from the x-axis is 2r.
Since pitch is equal to 2r, qB2πmvcosθ=2qBmvsinθ
