Help me solve this question asap a) Explain why a charged particle is moving in a circular path in a uniform b) A particle of charge 3.2 x 1019 C and velocity of 2 x 105 ms1 enters a magnetic field. uniform magnetic field of magnetic field strength, 0.2 T. If the particle moves in circular path of radius 4.0 cm, calculate the mass of the charged particle. Write the expression for the force acting on an electron carrying a charge e moving with velocity v when it enters perpendicularly into a) (i) an electric field of intensity E (i) a magnetic field of intensity B b) Sketch two separate diagrams of the direction of field, velocity and path of the electron and the force acting on it for the motion in part (a) (i) and (ii). c) With reference to your diagrams, state two differences between the electric field and magnetic field. d) A helium ion of charge +2e and mass 6.6 x1027 kg is accelerated by a voltage of 2400 V. The accelerated ion then moves into a perpendicular uniform magnetic field of magnitude 0.24 T. Determine (i) the radius of circular path of the helium ion. (ii) the period of revolution of the helium ion. Given charge of electron 1.60 x 1019
