Question
The Bohr model of the hydrogen atom consists of an electron travelling in a circular orbit of radius 5.29 x 10-11 m around a proton. The attraction between the two gives the electron the centripetal force required to stay in orbit. Calculate the:
a. Electric force between the two particles.
b. Speed of the electron.
c. Electric field the electron experiences.
d. Electric potential difference the electron experiences.
a. Electric force between the two particles.
b. Speed of the electron.
c. Electric field the electron experiences.
d. Electric potential difference the electron experiences.
Answers
k =9•10^9 N•m²/C²,
e =1.6•10^-19 C.
r = 5.29•10^-11 m ,
m(electron) = m = 9.1•10^-31 kg
a.F =k•e²/r²,
m•v²/r = k•e²/r²,
b. v=sqrt(k•e²/m•r),
c. E =k•e/r²,
d.φ = - k•e/r,
e =1.6•10^-19 C.
