Question: What happens to electric flux if the charge inside a sphere is doubled?

What happens to electric flux when area is doubled?

When area enclosed by the charge is doubled, A’ = 2A. New electric flux is given by : So, if the area is doubled, the electric flux will also gets doubled. Hence, this is the required solution.

What happens to the net electric flux through the surface of a sphere if the charge inside the sphere doubled?

If the radius of the sphere is doubled, the flux remains the same as it was before. (The surface of the sphere has increased, but the electric field through that surface is weaker when it reaches the larger surface.) If the Gaussian surface is changed from a sphere to a cube, the flux remains the same.

When the radius of sphere is doubled what will be the effect on electric flux through it?

Even if the radius is doubled, then the outward electric flux will remain the same as [dfrac{q}{{{varepsilon _0}}}]. This is because the outward electric flux is independent of the distribution of the charges and the separation between them inside the closed surface. Hence, option D is the correct answer.

What is the electric flux through the sphere due to this charge?

According to Gauss’s law, the net flux through the sphere is zero because it contains no charge.

Is electric flux always positive?

Electric field lines are considered to originate on positive electric charges and to terminate on negative charges. … Field lines directed into a closed surface are considered negative; those directed out of a closed surface are positive.

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.

Does flux depend on radius?

Therefore, if a closed surface does not have any charges inside the enclosed volume, then the electric flux through the surface is zero. … We can use this electric field to find the flux through the spherical surface of radius r, as shown in (Figure).

Is the flux through a closed surface always zero?

The flux of a vector field through a closed surface is always zero if there is no source of the vector field in the volume enclosed by the surface.

Does area affect flux?

The concept of flux describes how much of something goes through a given area. … The larger the area, the more field lines go through it and, hence, the greater the flux; similarly, the stronger the electric field is (represented by a greater density of lines), the greater the flux.

What is not true for electric charge?

Answer: D is not true charge of one electron is not one coloumb. Coulomb is very big unit of charge.

How does electric flux change with 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.
