2. Let a and c be fixed positive numbers. Consider the two surfaces 3₁ = √² - (2)² (x² + y²) and : z : 2 = √√x² + y² in R³. Let V be the solid body bounded by the two surfaces, i.e., the finite region above S2 and below S₁ in R³. S₁ = S₂ns (where S S2 The boundary surface S of V is the union of S₁ S is the part of S belonging to S₁ for i = 1,2). 1. Calculate the volume of V. 2. Calculate the outward pointing unit normal vectors for S₁ and for S2. = Si n S and 3. Calculate the outward flux cross S of the vector field F y = - ·1 + X z2 -j + k. a a
