question_answer1) 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 -1: For a mass M kept at the canter of a cube of side 'a' the flux of gravitational field passing through its sides is \[4\pi \] GM. and 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 \[\frac{1}{{{r}^{2}}}\], 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.

Its linear density (mass/length) varies with x as \[k{{\left( \frac{x}{L} \right)}^{n}}\], where ?n? can be zero or any positive number. If the position \[{{x}_{CM}}\] of the centre of mass of the rod is plotted against ?n?, which of the following graphs best approximates the dependence of \[{{x}_{CM}}\] on n? AIEEE Solved Paper-2007
