A particle with charge q, moving with a momentum p, enters a uniform magnetic field normally. The magnetic field has magnitude B and is confined to a region of width d, where \(\mathrm{d}<\frac{\mathrm{p}}{\mathrm{~Bq}},\) The particle is deflected by an angle θ in crossing the field
- \(\sin \theta=\frac{\mathrm{Bqd}}{\mathrm{p}}\)
- \(\sin \theta=\frac{\mathrm{p}}{\mathrm{Bqd}}\)
- \(\sin \theta=\frac{B}{d}\)
- \(\sin \theta=\frac{\mathrm{p}}{8}\)
Answer
(A) = Bqd p
