Electric Field Intensity

Electric field intensity due to finite and infinite line chargeConsider a line charge, from the point A to B with uniform charge densityConsider a small length dl of line charge Electric field at any point due to small length of line charge dl

Electric Field due to circular disc of charge

Electric field of the infinite sheet is normal to the plane of sheetHere the sheet is present in xy plane so its electric field present in z direction only
