What is the electric force between an electron and a proton placed 5.3 x 10^-11 m apart, the approximate radius of a hydrogen atom?
provides some pertinent background for this problem. Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which one of the naturally occurring electrons is removed. The radius of the orbit is 3.09 × 10-11 m. Determine the magnitude of the electron's centripetal acceleration.
Considering electron and proton as two charged particles separated by d = 4.6 × 10¬11 m calculate the Coulomb force between proton and electron. Take the electron charge –1.6 x 1019 C and 1 = 9 × 10° m/F. Give the answer in nano-Newtons (nN, 10° N). Απεο
An electron has a mass of 9.11x10-31 kg. In the Bohr model of the hydrogen atom, the electron was viewed as orbiting the lone proton of the nucleus; the centripetal force requirement was met by the electrical attraction between the oppositely charged proton and electron. The radius of orbit was 5.29x10-11 m. Use circular motion and electrostatic principles to determine the speed at which the electron moves as it orbits the proton.
An electron and a proton are separated by a distance of 1.9 x 10-10 m (roughly the diameter of a single atom). The masses of the electron and proton are me = 9.11 x 10- kg and 1.673 × 10-2' kg, respectively. The elementary charge mp e = 1.602 x 10-19 C. The universal gravitational constant G = 6.67 x 10 N-m²/kg² and the coulomb constant k = 8.988 × 10° N-m²/C2. What is the magnitude F, of the electric force between the electron and the proton? Fe= N. What is the magnitude F, of the gravitational force between the electron and the proton? Fg In this scenario, how many times stronger is the electric force than the gravitational force?

Supposing that an electron in a hydrogen atom ispositioned at an average distance of 5.29x10–11 m from the nucleus (so called Bohr radius of the atom), determine the Coulomb force of attraction between the electron and the proton (that is, the hydrogen atom nucleus at the center of the atom). The electron charge is –1.6x10–19 C, the proton charge is +1.6x10–19 C.

Say you have a point charge of one Coulomb and a hydrogen atom some distance away. Within what distance would the difference of forces on the proton and electron from the Coulomb charge exceed the attraction between the proton and electron that holds the hydrogen atom together. Treat the hydrogen atom as a proton and electron 0.53 × 10−10 m (a.k.a., one Bohr radius) apart.
