a) Compute the flux of the vector field F = (-2, 3, z³) across the disk in the xy- plane of radius 2, oriented with upward pointing normal vectors. Explain the result. - b) Is the flux across the top hemisphere of the sphere x² + y² + ² 4 oriented with outward pointing normal vectors equal to the flux across the disk just computed in part a)? Explain your reasoning.
