Electric potential at edge of disc
WebNov 29, 2014 · Find the electric field caused by a disk of radius R with a uniform positive surface charge density σ σ and total charge Q, at a point P. Point P lies a distance x away from the centre of the disk, on the axis through the centre of the disk. σ = Q πR2 σ = Q π R 2. To find dQ, we will need dA d A. Note that dA = 2πrdr d A = 2 π r d r. WebSep 12, 2024 · V = Ed = σd ϵ0 = Qd ϵ0A. Therefore Equation 8.2.1 gives the capacitance of a parallel-plate capacitor as. C = Q V = Q Qd / ϵ0A = ϵ0A d. Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor.

That force exists because free electrons go to the rim of the disc and create electric field, so we have: Fcp=e*E, E=m*ω^2*r/e. So potential diference is Δφ=∫Edr (from 0 to R), Δφ=mω^2*r^2/2e.
