An electron and a proton are moving along the same direction with the same kinetic energy. They enter a uniform magnetic field acting perpendicular to their velocities. The dependence of radius of their paths on their masses is:
- r \(\propto\) m
- r \(\propto \sqrt{m}\)
- r \(\propto \frac{1}{m}\)
- r \(\propto \frac{1}{\sqrt{\mathrm{m}}}\)
Answer
(B) r m
