An electron accelerated by a potential difference V = 1.0kV moves in a uniform magnetic field at an angle α=30∘ to the vector B whose modulus is B = 29mT. Find the pitch of the helical trajectory of the electron.

A non-relativistic charge q of mass m originates at a point A lying on x-axis and moves with velocity v at an angle alpha to the x-axis. A screen is located at a distance l from A. Find the
