Why is when D is tangential to the surface, D.ds = 0. * Because of the boundary condition between a dielectric surface to dielectric has no tangential component Because Gauss's law is an alternative formulation to obtain electric flux density and electric field intensity by the relation with electric charge Because of Divergence theorem and Stoke theorem Because when D is normal to the surface, D•ds = non-zero The accumulation of excess electric charge on an object is called * convection current O Eddy current O conducton current O Electric discharge O static electricity Two point charges -2 µC and 2 µC are located at (3,3,3) and (-3,-3,-3), respectively. Find the potential at (0,0,0). * 5.872 kV O O mv O 4.359 mv O 1.236 kV O 0.265 V
