Q. In New England, the horizontal component of the Earth's magnetic field has a magnitude of 1.6 x 10-5 T. An electron is shot vertically straight up from the ground with a speed of 2.8 x 106 m/s. What is the magnitude of the acceleration caused by the magnetic force? Ignore the gravitational force acting on the electron.

Q. A broad beam of light of 630 nm is normally incident on a thin, wedge-shaped film with an index of refraction 1.50. Light transmitted through the film gives 10 bright and 9 dark bands along the film length. What is the change in thickness of the film along its length.
