1) [1 mark] In the Bohr model of the hydrogen atom, an electron moves in a circular orbit around a proton. If the radius of this orbit is 5.3x10?¹¹ m and the speed of the electron is 2.2x10? m/s what is the magnetic field generated at the center of the atom by the electrons motion? i) 10.2 T ii) 11.7 T iii) 12.5 T iv) 13.2 T 2) [1 mark] For the same Bohr hydrogen atom as described above, what is the electric current density associated with the electrons motion? Assume the atom is spherical. i) 5.6x10¹? A/m² ii) 6.5x10¹? A/m² iii) 7.6x10¹? A/m² iv) 8.9x10¹? A/m² 3) [1 mark] An electric point charge of +2.0 nC sits at the geometric center of a cube of side length 1.0 cm. What is the net electric flux through this cube? i) 110 Nm²/C ii) 138 Nm²/C iii) 195 Nm²/C iv) 226 Nm²/C
