Question

2) The universe collapses and undergoes another big bang, resetting the electrical constant (k). In this universe, a distance of 5.3 x 10-11 meters separates the electron and proton in a hydrogen atom, and electrons orbit nuclei in perfect circles. The charges of protons and electrons have not changed. It is measured that the electron zooms around the proton at a speed of 141.9432215 m/s. Find k in this universe. Neglect gravitational forces.
[charge of proton = +1.60 x 10-19 C]
[charge of electron = -1.60 x 10-19 C]

Explanation / Answer

Centripetal force required = m*v*v/r = 9.109*10-31 * 141.9432215 * 141.9432215/(5.3*10-11) = 3.4627 * 10-16

F = k q1 *q2 /(r*r) = 3.462774 * 10-16

k = 97.2693 ans
