Name ____________________________ Date __________ Partners______________________________ Lab 2 – GAUSS’ LAW On all questions, work together as a group. The statement of Gauss’ Law: in words: The electric flux through a closed surface is equal to the total charge enclosed by the surface divided by . in symbols: The next few questions involve point charges. Draw the electric field lines in the vicinity of a positive charge +Q. Do the same for a negative charge -Q. Consider a outside of which a charge +Q lies. Remember, a “Gaussian sphere”, Gaussian surface is just a mathematical construct to help us calculate electric fields. Nothing is actually there to interfere with any electric charges or electric fields. Draw several electric field lines from +Q, but only ones that intersect the sphere. (For this question, omit field lines that don't intersect the sphere. This is to keep the drawing looking neat.) How much charge is enclosed by the sphere? Applying Law, what is the Gauss’ total electric field flux through the sphere? Justify your answer. Looking back at your drawing, field lines impinge on the spherical surface from the outside heading inward (this is defined as negative flux) and eventually impinge on another part of the surface from the inside heading outward (positive flux). Does it seem reasonable that the total flux through the sphere is exactly
