Q.1. As an application for the Lorentz force, two charged particles are travelling through a region of uniform magnetic field B that is directed into the page as shown in the figure below. The speed of the two particles is the same v = 1.3 105 m/s. The charge and mass of the particles are (q1,m1) and (q2,m2). The particles are deflected into the semi-circular paths exiting the magnetic field region at distances d1 and d2 from the entry point. 1. If |q1| = +3.2 10-19 C, m1 = 8.35 10-27 kg, and the distance d1 = 2.25 mm, then determine the magnitude of the magnetic field B. 2. If m2 = +3.34 10-27 kg, and the distance d2 = 1.81 mm, determine the sign and magnitude of the charge q2. 3. Determine the time spent by each particle in travelling the semi-circular path. ml dl (ql, ml, v) > B (q2,m2, v) d2 m2
