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,
