Question

1)A proton, which moves perpendicular to a magnetic field of 1.2 T in a circular path of radius 0.080 m, has what speed? (qp = 1.6 x 10-19 C and mp = 1.67 x 10-27 kg)


9.2 x 106 m/s
4.6 x 106 m/s
3.4 x 106 m/s
9.6 x 106 m/s

3)Two protons move with uniform circular motion in the presence of uniform magnetic fields. Proton one moves twice as fast as proton two. The magnitude of the magnetic field in which proton one is immersed is twice the magnitude of the magnetic field in which proton two is immersed. The radius of the circle around which proton one moves is r. What is the radius of the circle around which proton two moves?

4r
r
r/2
2r

7)A man stands underneath a power line carrying a current of 150 A. If the power line is 15 m above the man, what is the magnetic field measured by the man (Neglect the Earth's magnetic field).
