Question 1: A cube is defined by D=5x^(3)y^(2)ax-7x^(2)y^(3)ay(C)/(m^(2)),(a)grad1. If D=5x^(3)y^(2)ax-7x^(2)y^(3)ay(C)/(m^(2)),(a) Apply Gauss's law to find the total flux leaving the closed surface of the cube. (b) Evaluate grad. D at the center of the cube. (c) Estimate the total charge enclosed within the cube.
