At the end of the derivation, it is given(adsbygoogle = window.adsbygoogle || []).push({});

The electric fiel due to elementary ring at the point P is dE = [2∏rσdrx]/[4∏epsilon zero (x^2 +r^2)^(3/2)

]

To find the total E due to disc is given by

∏σx/4∏ε∫(2rdr)/(x2 + r2)3/2

I am stuck with the calculus done here to arrive at the solution. Please help me.

Thank You!
