Question

A positive charge is located at the center of a cube. a) are the intersections of the field lines with a side of the box uniformly distributed across that side? b) We can consider the left side of the box as composed of many small surface elements of equal area. i. Is the number of field lines through surface element A (a square at the center of the cube) greater than, less than, or equal to the number of field lines through surface element B ( a square at the edged of the cube? Explain ii Is the flux through surface element A >, <, or = to the flux through surface element B? Explain?
