In the bohr model of the hydrogen atom, an electron moves in a circular path around a proton. the speed of the electron is approximately 2.15 106 m/s?

This is an incomplete question, here is a complete question.

In the Bohr model of the hydrogen atom, an electron moves in a circular path around a proton. The speed of the electron is approximately ?

Find the force acting on the electron as it revolves in a circular orbit of radius .

Answer : The force acting on electron is,

Explanation :

Formula used :

where,

F = force acting on electrons

m = mass of electrons =

v = speed of electron =

r = radius of circular orbit =

Now put all the given values in the above formula, we get:

Thus, the force acting on electron is,

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

the answer is a and have a great day
