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 ?

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 ?

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?

An ice box is built of wood 1.75 cm thick, lined inside with cork 3 cm thick. If the temperature of the inner surface of the cork is 0^@C and that of the outer surface of wood is 12^@C , what is the temperature of the interface ? The thermal conductivity of wood and cork are 0.0006 and 0.00012 cgs units respectively.
