Homework Statement
In a hydrogen atom, the electron in orbit
around the proton feels an attractive force of
about 8.18 × 10−8 N.
If the radius of the orbit is 4.57 × 10−11 m,
what is the frequency in revolutions per second?
Answer in units of rev/s.
Homework Equations
Fc= mv^2/r
(2 pi r)
The Attempt at a Solution
(8.18 x 10^-8) x (4.57 x 10^-11)/ which mass? proton or electron?
pi( 2 x 4.57 x 10^-11)
