∙ 12y ago
The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward. The electric flux is then just the electric field times the area of the cylinder.

The relative distribution of charge density on the surface of a conducting solid depends on what?
the density of the conductor
What is the difference between a sodium and chloride ions?
Sodium has a positive charge of 1 while Chlorine has a negative charge of 1 when it is in its ionic form.
What is the difference between emulsoid and suspensoid in terms of affinity for solvent?
The difference between emulsoid and suspension in terms of affinity for solvent is that suspensoids have no affinity for the solvent. They are ready to fall out as soon as a charge is dispensed into the medium.
What is the difference between ferrous and ferric iron?
Ferrous ion carries a +2 charge and Ferric carries + 3
What is electrostatic attraction?
An electrostatic force attracts oppositely charged particles.

How does the capacitance of parallel plate capacitor vary with separation between plates of it?
capacitance is inversely proportional to the separation between the platesproof :-electric field is ;- k/E0where k- surface charge density of the plateand potential difference is given by kl/E0and, capacitance by C=Q/Vso, capacitance is inversely proportional to separation between the plates
Difference between a floating charge and a fixed charge?
fixed and floating charge
An isolated conducting sphere whose radius R equals 1M has a charge 1.1nc the energy density at the surface of sphere?
The energy density at the surface of a charged conductor is the surface charge density squared , divided by 2 x the permittivity of free space. The surface charge density is the charge divided by the area it sits on. So if, e = permittivity = 8.85 x 10^-12 CC/Nmm and D = surface charge density, and U = energy density and R = radius of sphere and q = charge on sphere, then; U = (1/2e) x D^2 where D = q/4piR^2 = 1.1 x 10^-9/(4 x 3.14 x 1) = 8.76 x 10^-11 , where 4piR^2 is the surface area of a sphere. So; D^2 = 76.7 x 10^-22 then ; U = (76.7 x 10^-22)/(17.7 x 10^-12) = 4.33 x 10^-10 Joules/mmm
What is Charge Density?
In electromagnetism, charge density is a measure of electric charge per unit volume of space, in one, two or three dimensions. More specifically: the linear, surface, or volume charge density is the amount of electric charge per unitlength, surface area, or volume, respectively. The respective SI units are C·m−1, C·m−2 or C·m−3.[1]Like any density, charge density can depend on position, but because charge can be negative - so can the density. It should not be confused with the charge carrier density, the number of charge carriers (e.g. electrons, ions) in a material per unit volume, not including the actual charge on the carriers.In chemistry, it can refer to the charge distribution over the volume of a particle; such as a molecule, atom or ion. Therefore, a lithium cation will carry a higher charge density than a sodium cation due to the lithium cation's having a smaller ionic radius, even though sodium has more electrons (11) than lithium (3).
What is the difference between a city criminal charge and a county criminal charge?
I live in Utah and I have found there is no difference
The difference between charge and current?
Charge is potential, current is flowing.
What is the amount of work done in moving a 100nc charge between two points 5 cm apart on an equipotential surface?
An equipotential surface has the same value of potential. Thus, work done would be zero. Work done = Charge X Potential difference
Difference in a charge between two electrodes in a cell causes a ----between electrodes?
Potential difference.
How is the charge distributed on a non-spherical conductor?
Charge density would be more where the curvature is more. So pointed surface would have max charge density. Hence there is a chance of electrical discharge at the sharp points. This is known as Corona Discharge or Action of Points
Difference between electrical current and electrical charge?
current is the flow of charge.
