1) Calculate the drift velocity v_G due to gravity of an electron located just above the surface of a white dwarf star. Note that the mass of the electron is 9.11 x 10^(-31) kg, the radius of the white dwarf star is 6.37 x 10^6 m (note that this is the same radius as the radius of the Earth), the mass of the white dwarf star is 1.2 solar masses (where 1 solar mass is 2 x 10^30 kg), the charge of the electron is 1.6 x 10^(-19) C, the magnetic field strength at the surface of the white dwarf is 10^5 T, and the gravitational constant is 6.67 x 10^(-11) m^3 kg^-1 s^-2. Assume that the force of gravity is perpendicular to the direction of the magnetic field. 1) Calculate the drift velocity v_G due to gravity of an electron located just above the surface of a white dwarf star.
