Question
A cube with 1.40 m edges is oriented as shown in the figure in a region of uniform electric field. Find the electric flux through the right face if the electric field, in newtons per coulomb ( N/C), is given by 8.20i. (N*m(shift-6)2/C)
Find the electric flux through the right face if the electric field, in newtons per coulomb ( N/C), is given by -3.60j.
Find the electric flux through the right face if the electric field, in newtons per coulomb ( N/C), is given by -2.80i + 3.00k.
What is the total flux through the cube for each of these fields?
Tries 0/10Explanation / Answer
Here ,
for the right face
Flux = E . A
flux = 8.20 i . (1.4^2 j)
flux = 0
the electric flux through the right face is 0 N.m^2/C
for E = -3.60 j
Flux = E . A
flux = -3.6 i . (1.4^2 j)
flux = - 7.06 N.m^2/C
the electric flux through the right face is - 7.06 N.m^2/C
for E - -2.80 i + 3 k
Flux = E . A
flux = ( -2.80 i + 3 k ) . (1.4^2 j)
flux = 0 N.m^2/C
the electric flux through the right face is 0 N.m^2/C
as the eletric field is uniform ,
according to gauss law ,
the net electric flux due to these fields is ZERO
