Uh, assuming by "spherical body" you mean "spherical shell of insignificant thickness" then it would just be 4*pi*(R^2)*sigma

Is voltage an excess accumulation of electric charge?
Sort of ... 1) Voltage is ALWAYS a comparison, thus it requires two reference points. 2) Its the density of the charge that counts, thus a gigantic charge over a very large area would result in a low voltage.
To find the acceleration of an object moving in a straight line you must calculate the charge in its speed during each unit of?
time
What is a hydrogrometer?
An instrument for measuring the Density of a liquid. The density of the Acid in a car Battery, changes as the stored electrici charge in the battery, is used to power things. A Hydrometer is commonly used to measure the Acid Density in Lead/Acid car batteries. The result of the Hydrometer reading let's you know how much electric charge is left in the battery. It is most commonly used to find out whether or not, the battery is old and depleted, or still in good condition. Go to Wikipedia to find out what a Hydrometer looks like.
What other physical quantities are quantized apart from charge?
Volume and mass or physical qualities related to weight and size of the actual specimen. Density, hardness, and molecular weight are physical qualities that are quantized based on the material.
Is density a qualitative or quantitative physical property?
basically it's a property that is EXACT normally ending with a number you see qualitative is something that is a very accuarate guess like odour "fishy or smelly" quantitave is density was; 1.45g/ml HOPE IT HELPED :) good luck !
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
What is the shape of equipotential surface due to a point charge?
concentric spherical surfaces
Which is the locus of a point at which potential due to an isolated point charge is constant?
That's a spherical surface, with the charge at the center of the sphere.
The relative distribution of charge density on the surface of a conducting solid depends on what?
the density of the conductor
Electric charge is uniformly distributed on the surface of a spherical balloon. Show how electric intensity and electric potential vary (a) on the surface (b) inside and (c) outside?

What is the Difference between line charge density and surface charge density?
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.
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 happens to the total flux through a spherical Gaussian surface surrounding a point charge when the charge is moved to another location inside the surface?
The total flux through any closed surface remains constant as long as the totalamount of charge inside it remains constant, regardless of how the surface isshaped, where inside the charge is located or how it's distributed inside.One might even go so far as to say that [ div E = Q ]
How do you calculate the electric field inside a conductor?
A spherical conductor with a radius of 14.0 cm and charge of 26.0 microcoulombs. Calculate the electric field at (a)r=10.0cm and (b)r=20.0cm and (c)r=14.0 from the center.
How mechanically a spherical condenser can be formed?
An electric charge cannot be carried in the interior of a hollow container. Due to mutual repulsion, the charges will migrate to the larger external surface.
