Radius of Gyration Formula

Equation for calculate radius of gyration is,

r_g = [m.v_⊥] / [|q|.B]

where,
m = the mass of the particle,
q = the electric charge of the particle,
B = the strength of the magnetic field,
v_⊥ = velocity perpendicular to the direction of the magnetic field,
r_g = radius of gyration, Gyroradius, Larmor radius or cyclotron radius
