This question contains Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best describes the two statements. Statement - I: For a mass $$M$$ kept at the centre of a cube of side '$$a$$', the flux of gravitational field passing through its sides is $$4\pi GM$$. Statement - II: If the direction of a field due to a point source is radial and its dependence on the distance '$$r$$' for the source is given as $$1/r^2$$, its flux through a closed surface depends only on the strength of the source enclosed by the surface and not on the size or shape of the surface.
