=======================================================
00:00 Introduction: Magnetic Field (Chapter 34)
00:34 Exercise: Question - 38 to 44: Magnetic Field (Chapter 34)
38. A particle of mass m and positive charge q, moving with a uniform velocity v, enters a magnetic field B as shown in figure (34-E13). (a) Find the radius of the circular arc it describes in the magnetic field. (b) Find the angle subtended by the arc at the centre. (c) How long does the particle stay inside the magnetic field? (d) Solve the three parts of the above problem if the charge q on the particle is negative.
1:52:30 Question - 45 to 48: Magnetic Field (Chapter 34)
45. Two particles, each having a mass m are placed at a separation d in a uniform magnetic field B as shown in figure (34-E19). They have opposite charges of equal magnitude q. At time t = 0, the particles are projected towards each other, each with a speed v. Suppose the Coulomb force between the charges is switched off. (a) Find the maximum value v of the projection speed so that the two particles do not collide.
