Difficult to imagine!

A charged particle of mass $\displaystyle m$ and charge $\displaystyle q$ is released from the origin with a velocity $\displaystyle \vec{v} = v_o \hat{i}$ in a uniform magnetic field $\displaystyle \vec{B} = \frac{B_o}{2}\hat{i} + \frac{\sqrt{3}B_o}{2}\hat{j}$

If $\displaystyle R$ represents the pitch (in meters) of the helical path described by the particle, the find the value of $(R-11)$ to the nearest integer .

Details and Assumptions:
$\bullet$ Consider a standard Right-handed Cartesian coordinate system.
$\bullet$ $\displaystyle m = 0.1g$
$\bullet$ $\displaystyle q = 10\mu C$
$\bullet$ $\displaystyle v_o = 20 m/s$
$\bullet$ $\displaystyle B_o = 8 T$
