Directions: The following question contains statement-1 and statement-2. Of the four choices given, choose the one that best describes the two statements.
Statement-1: For a mass M kept at the centre of a cube of side a, the flux of gravitational field passing through its sides is 4πGM.
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/r2, 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.
- a)Statement-1 is true, statement-2 is false.
- b)Statement-1 is false, statement-2 is true.
- c)Statement-1 is true, statement-2 is true; statement-2 is a correct explanation for statement-1.
- d)Statement-1 is true, statement-2 is true; statement-2 is not a correct explanation for statement-1.

Directions: The following question contains statement-1 and statement...
Let A be the Gaussian surface enclosing a spherical charge Q.
Electric field at any point at a distance 'r' from the charge Q is:
Flux through the Gaussian surface,
Every line passing through A has to pass through B, whether B is a cube or any surface. It is only for Gaussian surface that the lines of field should be normal, assuming the mass to be a point mass.
Gravitational field, 
Flux,
Here, B is a cube. As explained earlier, whatever be the shape, all the lines passing through A are passing through B, although all the lines are not normal.
Statement-2 is correct because when the shape of the earth is spherical, area of this Gaussian surface is 4πr2. This ensures inverse square law.

Directions: The following question contains statement-1 and statement...
Explanation:
Statement-1:
- The statement is true because for a mass M at the center of a cube of side a, the gravitational field lines pass through the sides of the cube. The total flux through the cube is 4πGM.
Statement-2:
- The statement is also true. The flux of a field through a closed surface depends only on the strength of the source enclosed by the surface. In this case, the field is radial with a dependence of 1/r^2, so the flux is independent of the size or shape of the surface.
Therefore, both statements are individually true. Statement-2 provides an explanation for why the flux in Statement-1 is 4πGM, as it depends only on the enclosed source and not the shape or size of the surface. Hence, option 'C' is the correct answer.
