Finding Centripetal Acceleration?

Click For Summary
SUMMARY

The discussion focuses on calculating the centripetal acceleration of an electron in the Bohr model of the hydrogen atom. The electron has a mass of 9.1 x 10^-31 kg, orbits at a radius of 5.3 x 10^-11 m, and revolves at a frequency of 6.6 x 10^15 revolutions per second. The correct formula for centripetal acceleration is Ac = 4π²f²R, which, when applied with the given values, results in a centripetal acceleration of 9.1 x 10^22 m/s². The user encountered difficulties in their calculations, indicating a need for careful application of the formula.

PREREQUISITES
  • Understanding of the Bohr model of the hydrogen atom

Homework Statement



In the Bohr model of the hydrogen atom, the electron revolves around the nucleus and has a mass of 9.1 x 10^-31 kg. If the radius of the orbit of the electron is 5.3 x 10^-11 m and the electron makes 6.6 x 10^15 r/s, find

The centripetal acceleration


Homework Equations


Ac= 4pi^2 X R/T^2

The Attempt at a Solution



I know it should be 4pi^2 X 5.4 X 10^-11/ 1/6.6 X 10^15 ^2

But... the answer is 9.1 X10^ 22 and I am NOT getting the right answer. I feel like there is something wrong within my operation.

Thanks!
