Verification of the divergence theorem on two given surfaces
Not what you're looking for?
Verify the divergence theorem (∫∫ (F.n) ds = ∫∫∫ (grad.F) dV) for the following two cases:
a. F = er r + ez z and r = i x + j y where s is the surface of the quarter cylinder of radius R and height h shown in the diagram below.
b. F = er r^2 and r = i x + j y + k z where s is the surface of the sphere of radius R centered at the origin as shown below.
Note: er, ez, i, j and k are unit vectors.
