If the radius of the Gaussian surface enclosing a charge is halved , how does the

electric flux through the Gaussian surface change ?

Does the charge outside the Gaussian surface contribute to total electric flux ?

Is electric flux a scalar or a vector ?

Force between two point electric charges kept at a distance d apart in air is F. If

these charges are kept at the same distance in water, how does the force between

them change?

In a medium, the force of attraction between two point electric charges, distance d

apart, is F. What distance apart should these be kept in the same medium so that t

force between them becomes 3F?
