Mdx + Ndy = Jax oy where 'C' is traversed in the positive (counter clock wise) direction. Example-30: Calculate the fhux of the vector field V = r7F through the surface S of a sphere of radius 'a, centered at the origin. 7 7 fffli ŽhAlsina divergence theorem)
flux for a vector field is given by the surface integral of that vector field. here the surface is a closed surface. For a closed surface, you can see, here in this case, r=a ever...
