Careful measurement of the electric field at the surface of a black box indicates that the net outward flux through the surface of the box is .
(a) What is the net charge inside the box?(b) If the net outward flux through the surface of the box were zero, could you conclude that there were no charges inside the box? Why or Why not?
Text solutionVerified
(a)
Electric field intensity, N/C
Magnitude of electric field intensity, N/C
Side of the square,
Area of the square,
The plane of the square is parallel to the y-z plane. Hence, angle between the unit vector normal to the plane and electric field,
Flux through the plane is given by the relation,
(b)
Plane makes an angle of with the x-axis. Hence,
Flux,
