Grade Summary Potential 100% (3% per attempt) Hint I give up Submit 3 20% Part (b) Write an expression for the electric flux 2 through S2. 20% Part (c) Write an expression for the electric flux , through S3. 20% Part (d) Determine the electric flux 4 through S4. 20% Part (e) write an expression for the electric flux 's through SS

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 = (1+3-8)/epsilon

Electric flux through the surface S1 = -4/epsilon

(b)

Electric flux through the surface S2 = Q1/epsilon = 1/epsilon

(c)

Electric flux through the surface S3 = Q2/epsilon

Electric flux through the surface S3 = 3/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 = 3-9 / Epsilon

Electric flux through the surface S5 = -6 / Epsilon
