When a charge Q is placed inside a cube What is the total electric flux coming out through any one face of the cube?
A charge q is placed at one corner of a cube. The electric flux through any of the three faces adjacent to the charge is zero.
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.
What is the total electric flux coming out of a unit positive charge kept in air?
4πε0
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.
When a charge Q is placed at the corner of a cube?
According to the Gauss Law, the total flux from a charge q is q/ε₀. If the charge is on the corner of a cube, some of the flux enters the cube and leaves through some of its faces. But some of the flux doesn’t enter the cube.
What is the charge enclosed in the cube?
zero
If the frame of reference is at the centre of the cube, the total flux passing through the cube would be zero (since both the faces P and Q would have equal distances from the reference and would cancel the electric flux) and hence the charge enclosed by the cube would be zero.
What is the charge enclosed by the cube?
What is the flux through a cube of side A If a point charge Q is at one of its corners?
If the charge ‘q ‘is placed at one of the corners of the cube, it will be divided into 8 such cubes. Therefore, electric flux through the one cube is the eighth part of \[\dfrac{q}{{{\varepsilon _\circ }}}\].
Is a positive charge is displaced against the electric field in which it was situated then?
If a positive charge is displaced against the electric field in which it was situated, then. work will be done by the electric field on the charge. the intensity of the electric field decreases. energy of the system will decrease.
What is the net electric charge inside the box?
Therefore, the net charge inside the box is 0.07 μC. Net flux piercing out through a body depends on the net charge contained in the body. If net flux is zero, then it can be inferred that net charge inside the body is zero.
How do you find the Q Enclosed of a sphere?
(One coulomb is equal to the magnitude of charge of 6.25 X 1018 electrons.) The charge enclosed in the sphere is then equal to the electric flux density on its surface times the area enclosing the charge. q (coulombs enclosed) = D x 4 r2.
