1. An alpha particle (the nucleus of a helium atom formed by 2 protons and 2 neutrons with charge q = +2(1.6 x 10-19 C ) is moving perpendicular to a magnetic field of 0.610 tesla at a velocity of 3.90E+6 m/s ; calculate the magnitude of the magnetic force exerted on it.
2. Calculate the acceleration of the alpha particle.
3. What will be the radius of curvature of the path followed by the alpha particle in the magnetic field?
