Question

10) in a region with a uniform electric field is given by E=( 2i + 6j + 8k)N/C ( vector form) . the electric flux through a sphere of radius 1m , centered at the origin is
a) 8 N-m^2/C
b) zero
c) 10 N-m^2/C
d) 16 N-m^2/C

Answer 1

Answer:

its ZERO(0) , as the only thing is that ,the sphere doesn't enclose any charge inside it.

in other words ,total field line passive through the spherical region comes out from it.,right ..

then net will be zero..for sure.

thankyou! be brainly.

hope u find my previous questions,and benifittd. I like helping like this ! thankyou...

Answer 2

Answer:

the answer is not the same only the number is different

Explanation:

As surface of area lies in the Y-Z plane, thus its area vector points in X direction  i.e.   A=20i^

Electric flux    ϕ=E.A

∴   ϕ=(5i^+4j^+9k^).(20i^)

⟹   ϕ=5×20=100 unit
