Explanation / Answer

net electric flux = net charge/eo

so flux though S1 = no charge -----> flux = 0

---------------------------

flux ( s2) = (q1+q2-q5)/eo = 4.2+8.5 -7 = 11.3 e-6/8.85 e-12 = 1.27 *10^6 Nm^2/C

--------------------------------------

flux ( S3) = q2+Q3-q6 = 4.2+0.5-10.6 = -5.9 e-6/(8.85e-12) = 6.67*10^5 Nm^2/C

----------------------

flux S4   =   q4-q5 = 9-7 = 2e-6/8.85e-12 = 2.259 *10^5 Nm^2/C

---------------------------------

flux S5 = q1+q2+q3+q4-q5-q6 = 4.2+8.4+0.5+9 -7-10.6

= 4.5 e-6/8.85 e-12  

= 5.084 *10^5 Nm^2/C
