r made even over g m e settled. This exercises to k q e settled over G m e settled and also the r squareds terminate. Then we replace in numbers and also we have the Coulomb'' s consistent times the primary fee settled, split by the gravitational continuous, times the mass of an electron settled. We obtain 4.16 times 10 to the forty-two which is a really enormous number. This indicates electrostatic pressure is way larger than the gravitational pressure for electrons. Currently when it concerns protons, the expression is primarily mosting likely to coincide however we'' ll have mass of a proton down right here rather than mass of an electron. So we replace in all the exact same numbers as prior to today the mass of electron which was 9.11 times 10 to the minus thirty-one kilos, is changed rather with 1.67 times 10 to the minus twenty-seven kilos, mass of a proton. This exercises to 1.24 times 10 to the thirty-six is the proportion of the electrostatic pressure to the gravitational pressure for protons. The factor these proportions are various is since the masses are various.">

This is University Physics Solutions with Shaun Dychko. We"re mosting likely to discover the proportion of the electrostatic pressure to the gravitational pressure in between 2 electrons and after that do it once more for in between 2 protons. So the electrostatic pressure is Coulomb"s continuous times both fees, both of which are the primary cost therefore we settle them, make even the primary cost, and also divide by the range in between both costs, and also the gravitational pressure is the gravitational continuous times the mass of each electron increased with each other, split by the range in between them made even. The proportion of these 2 pressures is mosting likely to be the electrostatic pressure split by the gravitational pressure. Currently as opposed to separating a portion by a portion, I"m mosting likely to increase by the mutual of this portion, so increasing by r made even over g m e made even. This exercises to k q e settled over G m e settled as well as the r squareds terminate. Then we replace in numbers as well as we have the Coulomb"s consistent times the primary cost settled, separated by the gravitational consistent, times the mass of an electron settled. We obtain 4.16 times 10 to the forty-two which is a really large number. This indicates electrostatic pressure is way larger than the gravitational pressure for electrons. Currently when it concerns protons, the expression is essentially mosting likely to coincide yet we"ll have mass of a proton down below rather than mass of an electron. So we replace in all the very same numbers as prior to and now the mass of electron which was 9.11 times 10 to the minus thirty-one kgs, is changed rather with 1.67 times 10 to the minus twenty-seven kilos, mass of a proton. This exercises to 1.24 times 10 to the thirty-six is the proportion of the electrostatic pressure to the gravitational pressure for protons. Due to the fact that the masses are various, the factor these proportions are various is.
