## What is the flux through a sphere?

Being a scalar quantity, the total flux through the sphere will be equal to the algebraic sum of all these flux i.e. This expression shows that the total flux through the sphere is 1/eO times the charge enclosed (q) in the sphere. The total flux through closed sphere is independent of the radius of sphere .

How do you calculate total outward flux?

Total flux ≈ ( ∂ P ∂ x + ∂ Q ∂ y + ∂ R ∂ z ) Δ V = div F Δ V . Total flux ≈ ( ∂ P ∂ x + ∂ Q ∂ y + ∂ R ∂ z ) Δ V = div F Δ V .

### What is net outward flux?

If net flux outwards flux the surface of the box is zero, then it can be inferred that there is no net charge inside the body. The body may have equal amount of positive and negative charges. Hence, net outward flux is zero.

What is the electric flux through A sphere that has A radius?

1.00 m
What is the electric flux through a sphere that has a radius of 1.00 m and carries a charge of +1.00 µC at its centre? Φ = EA E = 8.99 x 109 x 1 x 10-6/ 12 E = 8.99 x 103 N/C. The area that the electric field lines penetrate is the surface area of the sphere of radius 1.00 m.

## What is the outward flux of a vector field F?

You can use the divergence theorem to evaluate the outward flux of the vector field. In other words we can simply add up the divergence in the region bound by our surface S, in order to calculate the outward flux of our vector field across our surface S.

How do you find the result of electric flux through the sphere?

This makes E and n parallel to each other at each point on the sphere. Thus θ=0 and cosθ = 1 at any point on the surface of the sphere. (c) With E being constant in magnitude, and cosθ = 1 for all points, the total electric flux becomes: Φ = EAcosθ = (1800 N/C) [(4)(3.

### What is the electric flux through a sphere that has a radius?

What is the electric flux through out of the surface of the box?

The electric flux through a surface describes the number of electric field lines that cross that surface. Mathematically, it is defined as the surface integral of the electric field through that surface. Hence, for a closed surface, the electric flux can be computed without evaluating any integrals.

## What is the net flux of the uniform electric field?

The net flux of the uniform electric field through a cube oriented so that its faces are parallel to the coordinate planes is zero. This is because the number of lines entering the cube is the same as the number of lines leaving the cube.

What is the electric flux through the upper face of the box?

positive
The electric flux through the top face (FGHK) is positive, because the electric field and the normal are in the same direction. The electric flux through the other faces is zero, since the electric field is perpendicular to the normal vectors of those faces.
