## Find the angular velocity?

A charged particle in a magnetic field is spiralling along a path defined in cylindrical coordinates by
r = 1 m and

Theta = 2z rad (z is in meters).

The speed along the path is constant at V km/s with the value of V as given below.

Find the angular velocity, w. Give your answer in rad/s.
