Bohr's Orbit

  1. Nov 6, 2011 #1
    1. The problem statement, all variables and given/known data

    A particular Bohr orbit in a hydrogen atom has a total energy of -0.85eV. What are (i) the kinetic energy of the electron in this orbit, and (ii) the electric potential energy of teh system?

    2. Relevant equations


    KE= 1/2mv^2

    E = hc/lambda

    3. The attempt at a solution

    I'm a little confused in with this question. Wouldn't the KE be 0.85eV? and is the Potential energy given with mc^2?

    really appreciate any help given =)
