Let d be the region bounded below by the xy-plane, above by the sphere x2 y2z2-100, and on the sides by the cylinder x2 -64. set up the triple integral in cylindrical coordinates that gives the volume of d using the order of integration de dz dr

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
