Please show all equations and work

An alpha particle (nucleus of a helium atom) has a speed of 3x10^6 m/s and moves in a circle of radius 10 cm in the x/y-plane due to a uniform magnetic field. (a) What is the magnitude and direction of the magnetic field? (b) What is the cyclotron frequency of the alpha particle? (c) Through what potential difference was it accelerated? (d) What is its energy in units of electron-volts?
