Explanation / Answer

As we know that

Flux for a closed gaussian surface = Total charge enclosed by surface/epsilon

So,

(a)

Electric flux through the surface S1 = (Q1+Q2+Q3) / epsilon

Electric flux through the surface S1 = 2+4-8/epsilon

Electric flux through the surface S1 = -2/epsilon

(b)

Electric flux through the surface S2 = Q1/epsilon = 2/epsilon

(c)

Electric flux through the surface S3 = Q2/epsilon

Electric flux through the surface S3 = 4/Epsilon

(d)

Electric flux through the surface S4 = 0/epsilon

Electric flux through the surface S4 = 0 (Because charge enclosed by the S4 surface = 0)

(e)

Electric flux through the surface S5 = Q2+Q3 / epsilon

Electric flux through the surface S5 = 4-8 / Epsilon

Electric flux through the surface S5 = -4 / Epsilon
