A charged particle P leaves the origin with speed 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 x-axis for a minimum value of
.P will also strike T if
Both are correct.
Both are wrong.
The pitch of helix -
-For the minimum value of B, it is colliding after one pitch,it will collide with the target again if a pitch is halved or remains constant
