Which law helps to find total flux passing through a closed surface? State the law

Name the theorem used to find the electric flux through a surface enclosing charge.

Consider the points A(2,3,1) and B(3,-4,5). Write the direction ratios of the line passing through A and B.

A spherical Gaussian surface encloses a charge of 8.85 xx 10^(-8),C . (i) Calculate the electric flux passing through the surface (ii) If the radius of the Gaussian surface is doubled, how would the flux change?

A pair of equal and opposite charges sepa-rated by a small vector distance forms an electric dipole:- An electric dipole consisting of charges +20 mu C and -20 mu C separated by 2 mm is placed inside a cubi-cal box of side 10 cm. What is net electric flux passing though the box?
