A charged particle q enters a region of uniform magnetic field \(\stackrel{\rightharpoonup}{\mathrm{B}}\) (directed out of page as shown) and is deflected d after travelling a horizontal distance a. The magnitude of the momentum of the particle is
- \(\frac{\mathrm{qB}}{2}\left(\frac{\mathrm{a}^{2}}{\mathrm{~d}}+\mathrm{d}\right)\)
- \(\frac{\mathrm{qBd}}{2}\)
- \(\frac{\mathrm{qBa}}{2}\)
- zero
Answer
(A) qB 2 ( a ^ 2 ~d + d )
