What is electric field at Centre of cube?
The electric field at the centre of the cube, due to the eight charges, gets cancelled. This is because the charges are distributed symmetrically with respect to the centre of the cube. Hence, the electric field is zero at the centre.
What is the electric flux through one face of a cube?
Gauss’s law tells that the total flux through an area enclosing a charge Q is Qε0. Now as the cube is having six faces and as we can assume a symmetrical distribution of fluxes among its faces, the flux associated with one of its faces is Q6ε0.
What is the electric flux through the cube if a charge Q is placed at its Centre?
What is the electric flux passing through the cube? The flux passing through the cube = qε0.
When a point charge placed at corner of a cube then total flux through cube is φ What is the flux from each face of cube?
In these faces , electric field due at Q will be in the plane of faces , electric field due to Q will be in the plane of face and area is perpendicular to face hence flux ϕ′=EScos90∘=0. The flux through these three faces is zero.
How do you find the cube flux?
Apply the definition of flux: Φ=→E⋅→A(uniform→E), noting that a closed surface eliminates the ambiguity in the direction of the area vector. Through the top face of the cube Φ=→E0⋅→A=E0A. Through the bottom face of the cube, Φ=→E0⋅→A=−E0A, because the area vector here points downward.
What is the formula to find the center of mass?
The center of mass can be calculated by taking the masses you are trying to find the center of mass between and multiplying them by their positions. Then, you add these together and divide that by the sum of all the individual masses.
What charge is placed at the center of a cube?
A charge ′q′ is placed at the centre of a cube of side l. What is the electric flux passing through each face to the cube? As the charge is placed symmetrically to each face of the cube, thus electric flux passing through each face is equal to the (1/6)th of the total flux.
What is the total flux through the center of a cube?
Suppose a charge q is placed at the centre of the cube then total flux will be q/€. Since the charge is placed at the centre of cube , the flux will be symmetrically distributed along each face. Charge q is placed at the corner of a cube. What is the flux through one face of a cube?
What is the electric flux coming out of the cube face?
Due to symmetry, the amount of flux coming out of one cube face will be the same as the flux coming out of 1/6 surface of the sphere, and hence equal to q/6 coulombs. Therefore, electric flux (in coulombs) coming out of one cube face will be equal to 1/6 of the charge (in coulombs) placed at the centre of the cube.
Why is the charge on a cube symmetrically distributed along each face?
Since the charge is placed at the centre of cube , the flux will be symmetrically distributed along each face. Consider a sphere enclosing the cube and touching all the eight corners of the cube. It’s possible because cube is a symmetrical object.
