An electron moves in a circular orbit with a uniform speed v. It produces a magnetic field B at the centre of the circle. The radius of the circle is proportional to:
- \(\frac{\mathrm{E}}{\mathrm{~V}}\)
- \(\frac{\mathrm{v}}{\mathrm{E}}\)
- \(\sqrt{\frac{\mathrm{v}}{\mathrm{~B}}}\)
- \(\sqrt{\frac{E}{v}}\)
Answer
(C) v ~B
