Question

Compare the magnitude of coulomb and gravitational force between an electron and proton are separated by 1A° in hydrogen atom.​

Answer 1

Hope this helpzzz..!!!!!

Answer 2

The mass of an electron is 9.1094*10^(-31) kg and its charge is 1.6022*10^(-19) coulombs. Their separation 1 micrometre ( 1 UM) or 10^(-6) m. So the force of repulsion is (1.6022*10^(-19))^2/[4*pi*(4*pi*10^(-7))*10^(-12)] = 1.6256*10^(-21) newtons.
