Cov hluav taws xob teb ntawm lub nplhaib ntawm tus nqi ntawm lub axis ntawm lub nplhaib tuaj yeem pom los ntawm superposing tus nqi taw tes teb ntawm infinitesmal nqi ntsiab. Lub nplhaib teb tuaj yeem siv los ua ib qho khoom siv los suav cov hluav taws xob teb ntawm tus nqi them disc.

Yog li ntawd, qhov loj ntawm qhov hluav taws xob yog dab tsi?

tus qhov loj ntawm qhov hluav taws xob (E) tsim los ntawm tus nqi taw tes nrog tus nqi ntawm qhov loj Q, ntawm qhov taw tes qhov deb r deb ntawm tus nqi taw tes, yog muab los ntawm kab zauv E = kQ / r2, qhov twg k yog qhov tsis tu ncua nrog tus nqi ntawm 8.99 x 109 N m2/C2.

Qhov thib ob, lub zog hluav taws xob yog dab tsi? Ib hluav taws xob yog exerted ntawm ob yam khoom uas them. Cov khoom nrog tib tus nqi, ob qho tib si zoo thiab ob qho tib si tsis zoo, yuav tawm tsam ib leeg, thiab cov khoom nrog cov nqi sib txawv, ib qho zoo thiab ib qho tsis zoo, yuav sib nyiam.

Ib yam li ntawd, tib neeg nug, chav tsev hluav taws xob yog dab tsi?

The SI units ntawm hluav taws xob teb yog newtons per coulomb (N/C), los yog volts per meter (V/m).

Lub tshuab hluav taws xob siv hluav taws xob yog dab tsi?

Cov hluav taws xob siv zog ntawm ib qho taw tes yog lub zog uas tau ntsib los ntawm ib chav tsev zoo nqi tso rau ntawm qhov chaw ntawd. Fais Field Intensity yog vector kom muaj nuj nqis. Nws yog denoted los ntawm 'E'. Formula : Hluav taws xob Field = F/q. Unit of E is NC-1 lub Vm-1.
