In a hydrogen atom, an electron with a charge of (-)1.6E-19 orbits a proton with the same but positive charge at a distance 65 picometers away (that's trillionths of a meter or 10-12 m). What electric force F, in N, binds the two particles together? Use "E" notation for your answer.
Homework Answers
Solution:
Using the coulomb's law,
F = kQ2/r2
= 8.99*109 *[1.60*10-19]2/[65*10-12]2
= 5.45*10-8 N
= 5.45 E-18 N.
I hope you understood the problem and got your answers, If yes rate me!! or else comment for a better solutions

In the Bohr model of the Hydrogen atom, a single electron orbits around a single proton...
In the Bohr model of the Hydrogen atom, a single electron orbits around a single proton (which constitutes the nucleus). The mass of the electron (9.11x10-31 kg) is much less than the proton (1.67x10-27 kg), so the proton remains stationary while the electron moves around it. If the electron is 6.6x10-11 m away from the proton, calculate the magnitude of the electric force (in N) exerted by the proton on the electron. b) [Continued ...] In the Bohr model, an...

In an early model of the hydrogen atom (the Bohr model), the electron orbits the proton in uniformly circular motion. The radius of the circle is restricted (quantized) to certain values given by r = n^2a_0, for n = 1, 2, 3, ..., where a_0 = 52.92 pm. What is the speed of the electron if it orbits in (a) the smallest allowed orbit and (b) the seventh smallest orbit? (c) If the electron moves to larger orbits, does its...

The electron and the proton in a hydrogen atom have equal and opposite charges at adistance of 5.3×10−11m. What would be the mass of two particles with the samecharges as a proton and electron so that the gravitational force would be the samemagnitude as the electric force at this distance? Assume the two masses are the same. I know the correct answer is 2x10^-9 but can you please show my why in the simplest way including the formula you are...
