Question

What is the net flux of the uniform electric field of Exercise 1.15 through a cube of side 20 cm oriented so that its faces are parallel to the coordinate planes?

Answer 1

$\large{\underline{\boxed{\sf ANSWER}}}$

All the faces of a cube are parallel to the coordinate axes. Therefore, the number of field lines entering the cube is equal to the number of field lines piercing out of the cube. As a result, net flux through the cube is zero.

Answer 2

Answer:

All the faces of a cube are parallel to the coordinate axes.

Therefore, the number of field lines entering the cube is equal to the number of field lines piercing out of the cube.

As a result, net flux through the cube is zero.
