A)
B)
C)
D) All of the above
Correct Answer: C
Solution :
The integral form of Gausss law for gravity state\[\oint{_{\partial V}}g.\,ds=-4\pi Gm\] where \[\partial V\] is any closed surface, ds is a vector whose magnitude is the area of an infinitesimals small piece or surface \[\partial V\], and whose direction is the outward pointing surface normal, m is the total mass enclosed within the surface \[\partial V\]. The left hand side of this equation is called the flux of gravitational field. Flux of gravitational field is always negative (or zero) and never positive.
