## What is the surface charge density of a hollow sphere?

A hollow, conducting sphere with an outer radius of 0.253 m and an inner radius of 0.194 m has a uniform surface charge density of 6.96 × 10-6 C/m2.

## What is the surface charge density formula?

Suppose q is the charge and a is the area of the surface over which it flows, then the formula of surface charge density is σ = q/A, and the S.I. unit of surface charge density is coulombs per square meter (cm−2).

## What is surface charge density and unit?

Surface charge density is the quantity of charge per unit area. Surface charge density is denoted by . The SI unit of surface charge density is C m – 2 where, C = C o u l o m b and m = m e t e r .

## What is surface charge density and volume charge density?

Surface charge density represents charge per area, and volume charge density represents charge per volume. For uniform charge distributions, charge densities are constant.

## What is meant by surface charge?

Surface charge is a two-dimensional surface with non-zero electric charge. These electric charges are constrained on this 2-D surface, and surface charge density, measured in coulombs per square meter (C•m−2), is used to describe the charge distribution on the surface.
