Question

In an effort to better understand the behavior of atomic systems, the Danish physicist Niels Bohr (1885-1962) introduced a simple model for the hydrogen atom. In the Bohr model, as it is known today, the electron is imagined to move in a circular orbit about a stationary proton. The force responsible for the electron's circular motion is the electric force of attraction between the electron and the proton. The radius of the electron's orbit is 5.29×1011m, its mass is me=9.11×1031kg, and the electron's speed is 2.19×106m/s

If the nucleus had a charge of +2e (as would be the case for a nucleus of helium), would the speed of the electron be greater than, less than, or the same as that found for the hydrogen atom in the Bohr model? (Assume the radius of the electron's orbit is the same.)

which one???

(There are more parts to this question once the first question is answered. Please answer as I add to the question)

Explanation / Answer

Here electrostatic force provides necessary centripetal force

Fe=Fc

KQ1Q2/r2 )=mv2/r

Here given r is same

V^2 proportional to Q1Q2/m

If we ads chage speed i creases

I
