In the Bohr model of the hydrogen atom,
the speed of the electron is approximately
2.41 × 106 m/s.
Find the central force acting on the electron
as it revolves in a circular orbit of radius
4.92 × 10−11 m.
i used 9.10938188 × 10-31 as my mas and worked it out as follows many time and still come to a wrong answer.
F = mv^2 / r i used the numbers given plus that mass plugged them in and keep getting told i have the wrong answer help please :/.
