For Gauss's law we have to prove 1/£° time of charge ..... So We have E•dS where as E is electric field intensity and S is surface area of sphere now We have studied that E=kq/r^2 And k=1/4π£°(1 by 4 pie epsilon not) Now put value of both E and s in E•ds S=4πr^2 (4 pie r squ•) Now 4πr^2 and 4πr^2 will be cancel out and you will get 1/£°(1 by Epsilon not) Note:- for removing d you have have to take cos 0 because when you will draw a circle you will get to know why i took cos 0°(cos0°=1)
