Anyone here to help me:S ten dipoles, each consisting of two charges +- 19 uC, are located within a spherical surface, the radius of which is 2 mm. What is the flux density through the sphere i got 4.1*10^6 N-m^2/C ???????????

flux is zero man!!!

since there are dipoles inside......net charge inside is zero! apply gauss law......flux is zero!

ok....do u know gauss law for electrostatics?

gauss law states that net flux through a closed surface is NET CHARGE ENCLOSED by that closed surface...divided by epsilon nought......isnt it right?

so...u have dipoles here.....dipole means 2 charges , 1+ve,1-ve....so net charge of a dipole is zero......so even if u have 100 dipoles..net charge wud be zerro...so since there are only dipoles inside ur closed surface....net charge is zero..

since net charge enclosed by the closed surface is zero.....flux is zero by the gauss law....get it??????
