Question
A cube with 1.40 m edges is oriented as shown in the figure in a region of uniform electric field.
1.) Find the electric flux through the right face if the electric field, in newtons per coulomb (N/C), is given by 8.60i. (N*m(shift-6)2/C)
2.) Find the electric flux through the right face if the electric field, in newtons per coulomb ( N/C), is given by -4.80j
3.) Find the electric flux through the right face if the electric field, in newtons per coulomb ( N/C), is given by -3.00i + 3.80k
4.) What is the total flux through the cube for each of these fields?
Explanation / Answer
a) E = (8.6 N/C)i^ . (1.40 m)^2 j^ =0
b) E = (-4.8 N/C)j^ . (1.40 m)^2 j^ = -9.408 Nm^2/C
c) E = [(-3.00 N/C)i^ + (380N/C) k^].(1.40)^2j^ = 0
d) The total flux of a uniform field through a closed surface is always zero.
