    well i dont think negative energy makes much sense in this question

    Yes, since total energy and potential energy both are \(-ve\) and their ratio will be positive... (for electron)

    well since : 2 potential energy = total energy

    should the answer be 2 : 1 ? Well @UnkleRhaukus In the case of electron, both are negative

    total energy = -ve potential energy = - ve and hence : their ratio will be +ve

    I assume you're basing this on an electron orbiting a nucleus (which you need to say, otherwise this doesn't make any sense), in which case the virial theorem states that on the average, \[2T = -U \] where T is the kinetic energy and U is the potential energy. The total energy is thus \[ E = T + U = -\frac{1}{2}U + U = \frac{1}{2}U \]

    OK very right .. so the answer is 2 ?

    The ratio of total energy to potential energy is 1/2, but the ration of potential energy to total energy is 2.
