1. Consider a charged irregular shape enclosed by a Gaussian sphere of radius R. Which of the following statements is/are NOT true? a. The electric flux through the sphere is smaller when the irregular shape is moved a distance R/3 from the center but still inside the sphere. b. The electric flux through the sphere is not proportional to the charge of the irregular shape. c. You cannot use Gauss’ law to calculate the electric flux through the surface of the sphere. 2. A dipole with magnitude 3Q is placed inside the cavity of the solid conductor with net charge +7Q. What is the total charge at the outer surface of the conductor? 3. From Figure A, what is the net electric force on the charge +q0 located at the center of the square?
