using Gauss law
Flux = charge enclosed / epsilon_not
a)
only q1 encloses, so
F = 3.7*10^-6/(8.85*10^-12)
F = 4.181*10^5 Nm^2 /C
======
b)
since both charges enclosed by thegiven surface
F = ( 3.7 - 12.2)*10^-6 / (8.85*10^-12)
F = - 9.6*10^5 Nm^2/C
=======
c)
Since no charge enclosed
F = 0 Nm^2/C
=======
Comment in case any doubt, will reply for sure.. Goodluck
