27: Problem 27.21

INTRO:

Figure 1

-----------------------------------------------------------------------------------------------------
PART A:
What is the net electric flux through the cylinder of the figure (Figure 1)? Assume that Q = 250 nC and q = 8 nC.

SOLUTION:

The only charge that is important to us is the charge inside. 
Converting units... q = 8×10^-9 C

Φ_E = q/ε₀
Φ_E = (8×10^-9 C)/(8.854×10^-12 F/m)

→ Φ_E = 903.5 N⋅m²/C​
