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.

    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,
