Zolol [24]

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 2.15\times 10^6m/s?

Find the force acting on the electron as it revolves in a circular orbit of radius 5.34\times 10^{-11}m.

Answer : The force acting on electron is, 7.9\times 10^{-8}N

Explanation :

Formula used :

F=\frac{mv^2}{r}

where,

F = force acting on electrons

m = mass of electrons = 9.1\times 10^{-31}kg

v = speed of electron = 2.15\times 10^6m/s

r = radius of circular orbit = 5.34\times 10^{-11}m

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

F=\frac{(9.1\times 10^{-31}kg)\times (2.15\times 10^6m/s)^2}{5.34\times 10^{-11}m}

F=7.9\times 10^{-8}N

Thus, the force acting on electron is, 7.9\times 10^{-8}N
