4.Moving Charges and Magnetism
easy

A charged particle is projected in a plane perpendicular to a uniform magnetic field. The area bounded by the path described by the particle is proportional to

A

The velocity

B

The momentum

C

The kinetic energy

D

None of these

Solution

(c) $r = \frac{{\sqrt {2mK} }}{{qB}}$and $A = \pi {r^2} \Rightarrow A = \frac{{\pi (2mK)}}{{{q^2}{B^2}}} \Rightarrow A \propto K.$
