Question: What is the total electric flux emanating from a closed surface enclosing an alpha particle?

What is total electric flux emanating from closed surface enclosing an alpha particle?

qε=2eε0.

What is the total electric flux emanating from a closed surface?

Flux through a closed spherical surface around S1​ is given by ϕ=αt2 where α is a constant and t is time in seconds. … (2) Electric flux through a closed spherical surface around S2​ will be −αt2. (3) Rate of charge of electric flux through a closed spherical surface around S2​ will be −2αt.

What is the electric flux through a closed surface surrounding a dipole?

0(zero) because dipole has equal and opposite charge so net charge is zero and flux is also zero.

What is the electric flux linked with closed?

Gauss’s law for electricity states that the electric flux across any closed surface is proportional to the net electric charge enclosed by the surface. The law implies that isolated electric charges exist and that like charges repel one another while unlike charges attract.

What is alpha particle charge?

A positively charged particle ejected spontaneously from the nuclei of some radioactive elements. It is identical to a helium nucleus that has a mass number of 4 and an electrostatic charge of +2.

What is the net flux through the cube?

The net electric flux through the cube is the sum of fluxes through the six faces. Here, the net flux through the cube is equal to zero. … Therefore, quite generally, electric flux through a closed surface is zero if there are no sources of electric field, whether positive or negative charges, inside the enclosed volume.

What should be the flux linked with one face of a cube if a point charge Q is placed at one corner of that face of a 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.

What is the nature of Gaussian surface involved?

Explanation: The Gauss’s law in electrostatics gives a relation between electric flux through any closed hypothetical surface (called a Gaussian surface) and the charge enclosed by the surface. So, the nature of Gaussian surface is vector.

What is the net electric flux through a closed sphere enclosing an electric dipole?

The total flux across the sphere is. dependent on the position of dipole. The net charge enclosed by the sphere is zero.

What is the net electric flux passing through a closed square and closing an electric dipole?

Net electric flux coming out of closed surface is zero, because net charge on electric dipole is zero.

What is the total charge enclosed by a closed surface if the electric flux entering and leaving?

According to Gauss theorem, “the net electric flux through any closed surface is equal to the net charge inside the surface divided by ε0” .

What is the electric flux linked with surface?

If the electric field is uniform, the electric flux passing through a surface of vector area S is ΦE=E⋅S=EScosθ Φ E = E ⋅ S = ES cos ⁡ where E is the magnitude of the electric field (having units of V/m), S is the area of the surface, and θ is the angle between the electric field lines and the normal ( perpendicular ) …

What is the electric flux associated with surface?

Electric flux=charge inside/epsilon electric flux=q-q/ epsilon. electric flux=0. Electric flux is only depend on the charge present inside the enclosed surface and not present on the charge which are present outside the enclosed surface.

When the electric flux linked with a surface can be positive?

Positive flux means flux is leaving the hose; the hose is a source of flux. Negative flux is like water entering a sink; it is a sink of flux. So positive flux = leaving. Field lines directed into a closed surface are considered negative; those directed out of a closed surface are positive.
