and flux

it is point charge

the point is a charged particle

yes it is along axis

a disc of radius r we have to find electric flux at a point which is at a distance r from the centre i have used e=(sigma/2eo)(1-x/sqrt(r^2+x^2)) the area da=2pir*dr i know flux=closed integral (e.da) and x=r after that what should i do Reply With Quote

can u please elaborate a little.give me some starting eqn or something so that i can start the problem. please help.
