Determine the initial direction of the deflection of charged particles as they enter the magnetic fields shown in the figure below. B'in Bup X X %X % 3 R KRN XK XX j X X %X % 8 o @ Figure (a) The velocity is to the right, but what is the direction of the magnetic force? How do the velocity, magnetic field, and charge determ direction of the magnetic force? Figure (b) The magnetic field is upward, but what is the direction of the magnstic force? How do the velocity, magnetic field, and charge deta: direction of the magnetic force? Figure (c) The magnetic field is to the right, but this does not mean the magnetic force is in the same direction. What is the angle between th field and the velocity? Think about the magnetic force law and the cross product. How do the directions of the two vectors affect the force in this case? Figure (d) v
