Test 3, 13-Jul-01 Please overlay and name on outside 2) A Gaussian surface sits in electric field. The bolts show the course of field at the surface (accept to be opposite to the surface i.e. cos =1) and the field quality is shown at every side. Does the 3D square contain a positive net charge , negative net charge or zero net charge ? 1) What is the net flux  through a Gaussian surface encasing an electric dipole as demonstrated to one side ?? 0 +q - q 3) Shell of uniform positive charge encompasses a point charge (situated at the middle) of equivalent size however inverse sign. Two circular Gaussian surfaces are indicated. S1 is situated inside the charged shell while S2 is outside. Utilizing Gauss’ Law focus the E-field on S1 and S2 regarding the indicated amounts in figures (r1,r,q). E=0 at S2 and E=-kq/r1 2 at S1 +q - q r1
