b. An alpha particle has a charge of +3.2 x 10-19 C and mass 6.64 x 10-27 kg. The particle is moving perpendicular to a magnetic field at a velocity of 2.5 x 106 m/s to the left. The particle experiences a force of 3.0 x 10-13 N out of the page. What is the magnitude and direction of the magnetic field?
c. Using monochromatic light, an interference pattern is generated on a screen 50.0 cm away from a single slit. The width of the slit is 12 μm. The third dark fringe is 6.0 cm from the centre of the central maximum. What is the
