Question
1)A surface encloses the charges q1 = 3.2 C , q2 = 7.1 C , and q3 = -3.9 C .Find the electric flux through this surface.
2)
Four pairs of conducting spheres, all with the same radius, are shown in the figure,(Figure 1) along with the net charge placed on them initially. The spheres in each pair are now brought into contact, allowing charge to transfer between them.
Rank the pairs of spheres in order of decreasing magnitude of the charge transferred.
Rank from largest to smallest.

Explanation / Answer
Gauss's law may be expressed as
Phi_E = rac{Q}{ arepsilon_0}
where E is the electric flux through a closed surface S enclosing any volume V, Q is the total charge enclosed within S, and 0 is the electric constant
total charge , Q = q1 + q2 + q3
Q = 3.2 + 7.1 - 3.9
Q = 6.4 uC
electric flux , flux = Q/epsilon
flux = 6.4 * 10^-6 /(8.85 * 10^-12)
flux = 7.23 * 10^6 N.m^2/C
the electric flux through this surface is 7.23 * 10^6 N.m^2/C
