Webb28 dec. 2024 · To calculate the energy of an electron in a hydrogen energy level, E = -13.6eV/n 2, where n is the principal quantum number. The orbital radius is also fairly simple to calculate: r = r 0 n 2 where r 0 is the Bohr radius (0.0529 nanometers). WebbWorked example An aluminium window frame has a width of $40 \mathrm{~cm}$ and length of $73 \mathrm{~cm}$ as shown in the diagram below. The frame is hinged along the vertical edge AC. When the window is closed, the frame is normal to the Earth’s magnetic field with magnetic flux density $1.8 \times 10^{-5} \mathrm{~T}$. roma interested
