Gauss's Law Problem 1

Description

The animation shows several lines charges pointing out of the page and a cylindrical electric flux detector. The bar graph displays the electric flux (in units of Nm2/C) passing through the flux detector.  Drag the surface and observe flux readings. Note:  The Gaussian surface cannot enclose a portion of a line charge but may enclose two line charges.

Question

Which pair(s) of line charges is(are) identical in size but opposite in magnitude? Start Detector
