Question

find the magnitude of the force on an electron in the ground-state orbit of the bohr orbit

Answer 1

try the coulomb force

Answer 2

thanks it's f=(ke^2)/r^2

Answer 3

remember if you're going to use coulomb force, you have to take into account the number of protons in the nucleus as well.

You could also find the force as the centripetal force, which is just equal to the coulomb force anyway.

Answer 4

okay

Answer 5

I think you'd be justified in assuming r = "Bohr's radius", a commonly used distance in exercises such as these (which is the mean radius of an electron's orbit in atomic hydrogen, = 5.3 * 10 ^-10 m)
