Homework Statement
In bohr model of H atom, speed of electron/ e- is aproximately 2.20x10^6 m/s
a) find force acting on e- as it revolves in a circular orbit of radius 0.530x10^-10
b) the centripital acceleration of the e-
Homework Equations
[tex]\sum F= ma= m(v^2/r)[/tex]
The Attempt at a Solution
Well I'm not sure if I'm going in the right direction ...
does the electron have a x and y component of force?
a) m e-= 9.109x10^-31 kg
[tex]\sum F= ma= m(v^2/r)[/tex]
(9.109x10^-31kg) ( (2.20x10^6)^2/ 0.530x10^-10)= 8.32x10^-8 N
b)
[tex] a_c= v^2/r = 9.13x10^ 22 m/s^2 [/tex]
can someone see if this is alright for me?
Thanks
