Physics 2102, January 30, 2011, Activity 1 The figure shows three situations in which a Gaussian surface (cube) sits in an electric field. The arrows indicate the directions of the field lines, and the values are the magnitudes of the electric flux through each face (in Nm 2 /C). (The lighter arrows are for the hidden faces). Indicate which of the cubes (if any) enclose a net positive charge: Activity 2 A point charge q is at the center of a sphere with area A . The electric flux through the sphere is Φ . (a) What would be the electric flux through a larger sphere with area

Unformatted text preview: 2A – would it be smaller than , the same as , or larger than Φ ? (Circle the right answer). (b) What would be the electric flux through the original sphere if the charge was 2q instead of q – would it be smaller than , the same as , or larger than Φ ? (Circle the right answer). (c) What would be the electric flux through the larger sphere if the charge was 2q instead of q- would it be smaller than , the same as , or larger than Φ ? (Circle the right answer)....
