The flux doesn’t depend on the distance r. We would get the same result no matter the size of the closed surface around the point charge.
Is electric flux affected by radius?
How does the electric flux due to a point charge enclosed by a spherical Gaussian surface get affected when its radius is increased? … That is, on increasing the radius of the gaussian surface, charge q remains unchanged. So, flux through the gaussian surface will not be affected when its radius is increased.
Why flux does not depend on radius?
If the radius of the spherical Gaussian surface is doubled, the surface area will increase by 4 times. On the other hand, the electric field at all points on the bigger surface will decrease by a factor of 4. Hence the flux through the surface remains the same.
Does flux depend on location?
The total flux is insensitive to the exact location of the charge within the surface. Now if you want to calculate the total flux through a part of the total surface, then it depends on the location of the charge in general.
At what angle electric flux is minimum?
The electric flux through the surface is minimum when the angle between e and a is. salonitomar2770 is waiting for your help.
Which does not affect electric flux?
It is important to note that while the electric flux is not affected by charges that are not within the closed surface, the net electric field, E, in the Gauss’ Law equation, can be affected by charges that lie outside the closed surface.
How do you solve electric flux?
Solution: electric flux is defined as the amount of electric field passing through a surface of area A with formula Φ e = E ⃗ ⋅ A ⃗ = E A cos θ Phi_e=vec{E} cdot vec{A}=E,A,costheta Φe=E ⋅A =EAcosθ where dot ( ⋅) is the dot product between electric field and area vector and θ is the angle between E and the …
Is electric flux directly proportional to electric field?
It measures the charge enclosed inside the surface where we are measuring the electric flux. We already know electric flux is the number of field lines passing through any arbitary area or surface. So we can say electric flux is directly proportional to the electric field lines.
Why is flux the same?
Since the electric field is parallel to the normal of the surface at all points, the flux is simply the electric field at that distance multiplied by the area of the element.
Can flux be negative?
The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. If a net charge is contained inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if it is positive, negative if it is negative.
