This question contains Statement -1 and Stantement -2 Of the four choices given after the statements, choose the one that best desctibes the two statemesnts. Statement -1: For a mass M kept at the center of a cube of side 'a', the flux of gravitational field passing through its sides 4piGM. Statement -2: If the direction of a field due to a point source is radial and its dependence on the distance 'r' from the source is given as (1)/(r^2) , its flux throught a closed surface depends only on the strength of the source enclosed by the surfcae and not on the size or shape of the surface.
