1. (A) Find the de Broglie wavelength (in nm) associated with an electron that is moving with a velocity of 2310 km/s. The electron rest mass is 9.11 x 10-31 kg. Note, electrons having this speed would need to be treated as waves in atoms because the wavelength is on the order of the size of atoms. (B) A baseball weighs 220 g.

In
the Bohr model of the atom, an electron can be thought of a small
sphere that rotates around the nucleus. In a hydrogen atom, an
electron (me=9.11 x 10^-31 kg) orbits a proton at a distance of 5.3
x 10^-11 m from the proton. If the proton pulls on the electron
with a force of 9.2 x 10^8 N, how many revolutions per second does
the electron make?
