Question: the most common isotope of hydrogen contains an electron and proton seperated byb about 5x10^-5m. The elementary unit of charge is 1.6x10^-19 C. Determine the force of attraction between the two particles. I would really love to know how to solve this problem, I know I would use the distance and the 9x10^9, but what else would I use? Thank You!

It will be simple equation Energy of attraction = (1.6*10^(-19))^2/(5*10^(-5)) =0.5*10^(-33 )J Now multiply this with 1/(4 pi e0) e0=8.8 *10^-9 The energy will be 0.5/(4 pi 8.8) 10^(-24) J=4.52*10^(-21) J This will be the answer. Your multiplication number is e0. It should be 1/9 *10^9
