Question

The electric field in a certain region of space is E -10'INC-1. How
much is the flux passing
through an area 'A' if it is a part of XY plane. XZ
plane, YZ plane, making an angle 30' with the axis​

Answer 1

Use $\phi = \overrightarrow{E}.\overrightarrow{A}$

Explanation:

Given that,

$\overrightarrow{E} = 10^4\widehat{i}$

We have a relationship for Electric Flux,

$\phi = \overrightarrow{E}.\overrightarrow{A}$

For xz plane,

$\phi = 10^4 (i.j) = 0$

For yz plane,

$\phi = 10^4A$

• In electromagnetism, electric flux can be called as upon a surface known, the electric field being measured.

We know that,

It the electric field only which can't flow by itself.

• If a point is taken some distance apart from any charge, then the field being described that causes the field, can be referred to as Electric Field.

Answer 2

The flux passing through an area is 5√3 × 10³ A

Explanation:

The electric flux is given by the formula:

F = E . A = EA cos Ф

Φ is the angle between plane area and axis

For XY plane ⇒ Φ = 0°

F = EA cos Ф = EA cos 0 = EA = 10⁴ A

For YZ plane ⇒ Φ = 90°

F = EA cos Ф = EA cos 90 = 0

For XZ plane ⇒ Φ = 90°

F = EA cos Ф = EA cos 90 = 0

The plane is making angle of 30° with axis, thus the flux is:

F = EA cos 30 = 10⁴A √(3/4)

∴ F = 5√3 × 10³ A
