Then, everywhere. c) d) The graph of is the limit of triangles with base extending from to e) and vertex at . at the point . Subjective Problems 1) Prove that for a scalar field where the surface S has the boundary C. 2) Compute the divergence of the function Check the divergence theorem for this function, using your volume as the inverted hemispherical bowl of radius R, resting on the xy-plane and centred on the origin. [Use and ] 3) What is the charge density of a uniform, infinitesimally thin spherical shell of radius R and total charge Q, centred at the origin?
