A charged particle is projected in magnetic field

→

= 10

T from origin in X – Y plane. Theparticle moves in a circle and just touches a line y = 5m at x = 5√3 . Then (mass of particle= 5 × 105kg and charge 1µc

The particle is projected at an angle 60° with X – axis
The radius of circle is 10m
Speed of particle is 2m/s
Work done by magnetic force on the particle is zero
