Answer 2

Answer:

The net electric flux passing through the sphere is 3.14 × 10⁵ Nm²/C.

Explanation:

Given:

The electric field (E)

E = 10³ N/C

And the radius of sphere (r) = 1

To Find:

The net electric flux passing through the sphere (φ).

Calculation:

As shown in the diagram the electric field is entering through the left and leaving through the right portion of the sphere.

So, the area which is being cut by the electric field is not the whole sphere but the cross-section of it.

Hence, the electric flux is given as:

φ = E.A

⇒ φ = E × πr²  (As area of cross-section looks like a circle)

⇒ φ = 10⁵ × 3.14 × (1)²

⇒ φ = 3.14 × 10⁵ Nm²/C

Therefore, the net electric flux passing through the sphere is 3.14 × 10⁵ Nm²/C.
