In this worksheet, we will practice relating the electric flux through a closed surface to the charge contained by that surface.

Q1:

A point charge of 10 µC is at an unspecified location inside a cube of side length 2.0 cm.
Find the net electric flux through the surfaces of the cube.

A
N⋅m^{2}/C

B
N⋅m^{2}/C

C
N⋅m^{2}/C

D
N⋅m^{2}/C

E
N⋅m^{2}/C

Q2:

The electric field in a region is given by , where ,
, and . What is the net charge enclosed
by the shaded volume shown?

A
C

B
C

C

Q3:

The cross-sections of the closed surfaces (a), (b), (c), and (d), are shown in the accompanying diagrams.
