Question 2
Consider a 1000. Gauss magnetic field along the z axis and a proton moving with an instantaneous velocity of = 3 + 4 km/s (note its speed is 5. km/s composed of 3. km/s along the x axis and 4. km/s along the z axis).
Determine the radius of its spiraling orbit. proton: 1.67 10-27 kg and 1.6 10-19 Coulomb
