1.
A cube has sides of length 0.250 m.
One corner is at the origin, and the furthest corner
is at (
x
,
y
,
z
) = (0.25m, 0.25m, 0.25m).
One side of the cube is in the
x
,
y
plane; one side
is in the
x
,
z
plane; and one side is in the
y
,
z
plane. There is a uniform electric field
everywhere
E
= 150 N/C
i
+
115 N/C
j
.
a) Calculate the electric flux through each of the six sides of the cube. Side 1 is the
side in the
x
,
y
plane; side 2 is the side parallel to side 1. Side 3 lies in the
x
,
z
plane;
side 4 is the side parallel to side 3. Side 5 lies in the
y
,
z
plane; side 6 is the side
parallel to side 5.
