Unformatted text preview: surface. Check that the input power is equal to the rate of the increased total energy. 2. Consider an infinite parallel-plate capacitor, with the lower plate carrying the charge density – and the upper plate carrying the charge density + . (a) Determine all nine elements of the stress tensor, in the region between the plates. Display your answer as a 3x3 matrix: zz zy zx yz yy yx xz xy xx T T T T T T T T T (b) Use the stress tensor to determine the force per unit area of the top plate....
