What is the radius of the circular orbit for a proton with speed 7.0x104 m/s?
Express your answer with the appropriate units.
Suppose that an electron is moving with a velocity of 4 x 106 m/s in a uniform magnetic field of 0.4 T.
perpendicular to the direction of the magnetic field. The charge on electron is 1.60 × 10-19C.
1. Find the radius of the circular orbit that an electron will make in this uniform magnetic field.
2. If the proton is moving with the same velocity in the same magnetic field, what will be the radius of
the path of the proton.
Compare the radii of both paths (for electron and proton) and compare it with the mass ratios of both
particles.
A deuteron (the nucleus of an isotope of hydrogen) has a mass of 3.34x10-27
