(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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-

2. Relevant equations

[tex]\sum F= ma= m(v^2/r)[/tex]

3. 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
