K E space equals space fraction numerator 2 pi e to the power of 4 m end exponent over denominator 4 h squared end fraction space equals space fraction numerator h squared e to the power of 4 m end exponent over denominator 2 h squared end fraction space equals space fraction numerator pi squared m over denominator 2 h squared end fraction e to the power of 4
space space a subscript 0 space space end subscript equals space space fraction numerator h squared over denominator 4 h squared e squared m end fraction
S o comma space space space e subscript 4 space space equals space space fraction numerator h to the power of 4 over denominator 16 pi to the power of 4 m squared a squared end fraction
H e n c e comma space K E space space equals space fraction numerator h squared over denominator 32 pi squared space m a squared end fraction
