Question 11
(a) (i) Define the term neutral points as used in magnetism.
(ii) Draw a diagram showing the pattern of a magnetic field around a bar magnet.
(b) A particle of charge 3.2 x 10-19 C enters a uniform magnetic field with a speed of
5.0 x 107 m s-1. If the magnetic field strength is 8 T, Calculate the maximum force that can be experienced by the particle.
(c) (i) State the condition necessary for resonance in an R-L-C series circuit.
.
The diagram above illustrates an electrical circuit diagram. Use it to calculate the:
(i) value of R;
(ii) current through R.
