Careful measurement of the electric field at the surface of a black box indicates that the net outward flux through the surface ofthe box is `8.0x10^3Nm^2//C`.
If the net outward flux through the surface of the box were zero, could you conclude that there were nd charges inside the box ? Why or why not ?

Careful measurement of the electric field at the surface of a black box indicates that the net outward flux through the surface ofthe box is 8.0x10^3Nm^2//C . What is the net charge inside the box ?

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 8.0 xx 10^(3)N*m^(2)*C^(-1) . (a) What is the net charge inside the box? (b) If the net outward flux through the surface of the box where zero, could you conclude that there where no charges inside the box? Why or why not ?

If the inward and the outward electric flux through a closed surface be phi _(1) and phi _(2) , the charge inside the closed surface is

Due to the presence of a charge at the centre of a sphere of radius 10 cm, the electric flux passing through the surface of the sphere is -6xx10^(3)N.m^(2).C^(-1) . (i) What is the magnitude of charge inside the sphere? (ii) If a concentric spherical Gaussian surface with a radius double that of that of the sphere is taken, what will be the amount of electric flux now passing through this surface?

In a region, the intensity of an electric field is given by vecE=2hati+3hatj+hatk in NC^(-1) . The electric flux through a surface vecS=10hatim^(2) in the region is
