The figure attached shows an ion with a mass of 2.18 x 10-26 kg and charge +1.60 x 10-19 C, moving through a velocity selector with a speed of 1.02 x 103 m/s. A uniform magnetic field inside and outside velocity selector is 0.930 T. a) Calculate the magnetic force exerted on the ion. State the direction of the force. b) Calculate the magnitude of the electric field required to ensure that the ion moves without deflection. c) As the ion leaves the velocity selector, the ion starts moving in a circular motion due to magnetic force. Calculate the radius of the path. d) Explain how ions with larger mass deflect when moving through a magnetic field.
