Part A Which of the following statements about Gauss's law are correct? (There may be more than one correct choice.) Choose all that apply. If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface ) Gauss's law is valid only for symmetric charge distributions, such as spheres and cylinders. Only charge enclosed within a Gaussian surface can produce an electric field at points on that surface. The electric flux passing through a Gaussian surface depends only on the amount of charge inside that surface, not on its size or shap ( If there is no charge inside of a Gaussian surface, the electric field must be zero at points of that surface. Submit Request Answer de FeedbackProblem 3: A point charge of 5.5 JC is at the center of a cubical Gaussian surface 12 cm on edge. What is the electric flux through one face of the cube? Problem 4: A point charge causes an electric flux of -750 Nm /C to pass through a spherical Gaussian surface of 10.0 cm radius centered on the charge. a) If the radius of the Gaussian surface were doubled, how much flux would pass through the surface? b) What is the value of the point charge
