What is non-uniformly charged sphere?
1. When the point is outside the sphere. The whole charge on the sphere can be considered as to be concentrated at a single point and hence acts like a point charge. So the potential of the non-uniformly charged sphere can be the same as that of a point charge.
How do you find the charge of a sphere?
The uniform charge per unit volume ρ in the insulating sphere is its total charge (Q) divided by its total volume.
What is a non uniform charge distribution?
Charge is distributed non-uniformly throughout the volume of the distribution, which has radius of big R, and the charge density was given as a constant ρs times little r over big R, and little r is the location of the point of interest.
Can Gauss law be used for non uniform charge distribution?
How to do Gauss’s law with NON-uniform charge density inside a non-conducting material. The vast majority of Gauss’s law problems we do deal with uniform charge densities for non-conductors/insulators. Each little sphere has its own charge density value, and so the charge of each hollow shell is rho x dV.
What is a non uniform electric field?
Non uniform electric field is the one in which the electric field vectors are more closely spaced near the source charge and they get far apart as the distance from the source charge increases.
What does uniform charge mean?
This means charge per unit area over the surface is a constant. Uniformly distributions means each cm^2 area will have 1C of charge . An area of 1mm^2 will have 0.01 C of charge. Thus the charge is evenly distributed .
What charge does a sphere carry?
Sphere 1 has a charge of −4,8×10−18C. Sphere 2 has 60 excess electrons.
What is the new charge on each sphere?
One of them carries +6 μC and the other −12 μC. The two spheres are carefully brought in contact and then separated. What is the new charge on each sphere if……solution.
| Q1 = Q2 = | −6 μC | = −3 μC |

What causes non uniform electric field?
On the other hand, if the electric field is nonuniform, the force on each of the two poles of the dipole is not equal; therefore, the net force is not equal to zero and there is movement of the particle.
What happen when electric field is non uniform?
An electric dipole always experiences a torque when placed in uniform as well as non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So the electric dipole in non-uniform electric field experiences both torque and force.
Is charge density a uniform?
Charge on a conductor would be free to move and would end up on the surface. This charge density is uniform throughout the sphere. Charge Q is uniformly distributed throughout a sphere of radius a. That is, the electric field outside the sphere is exactly the same as if there were only a point charge Q.
What is the symbol of charge density?
letter ρ
Volume charge density (symbolized by the Greek letter ρ) is the quantity of charge per unit volume, measured in the SI system in coulombs per cubic meter (C⋅m−3), at any point in a volume.
Is the charge density of a sphere uniform?
This charge density is uniformthroughout the sphere. Charge Q is uniformlydistributed throughout a sphere of radius a. Find the electric field at a radius r. First consider r > a; that is, find the electric field at a point outsidethe sphere.
Is the electric field in the sphere of uniform charge zero?
That is, the electric field insidethe sphere of uniform charge is zeroat the center and increases linearlywith radius r: Of course, the two expressions for the electric field match — have the same value — at the surface of the sphere, for r = a.
How to calculate the charge of a sphere?
Just as before (for the point charge), we start with Gauss’s Law Just as for the point charge, we find and we know which means E = k Q / r2 That is, the electric field outsidethe sphere is exactly the same as if there were only a point chargeQ. Now, move inside the sphere of uniform charge where r < a.
