The Total solution for NCERT class 6-12
What is the net flux ofthe uniform electric field of Exercise 1.15 through a cube of side 20 cmoriented so that its faces are parallel to the coordinate planes?
All the faces of a cubeare parallel to the coordinate axes. Therefore, the number of field linesentering the cube is equal to the number of field lines piercing out of thecube. As a result, net flux through the cube is zero.
