Hluav taws xob teb yog txhais raws li tus hluav taws xob ib unit nqi. Kev taw qhia ntawm lub teb yog coj los ua tus coj zog nws yuav siv sij hawm rau ib tug zoo kuaj nqi. Cov hluav taws xob teb yog radially sab nraud los ntawm tus nqi zoo thiab radially nyob rau hauv mus rau tus nqi tsis zoo.

Kuj paub, qhov txawv ntawm hluav taws xob thiab hluav taws xob yog dab tsi?

Heev txhais ntawm hluav taws xob teb yog thaj tsam ntawm qhov chaw ntawm txhua qhov chaw hluav taws xob yog exerted rau tus nqi. Tus naj npawb ntawm teb kab los ntawm tus nqi zoo yog muab proportional rau qhov loj ntawm tus nqi. Lub flux ib chav tsev ntawm txhua qhov chaw yog qhov hluav taws xob teb kev siv zog ntawm qhov ntawd.

Tsis tas li ntawd, 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.

Hais txog qhov no, kev sib raug zoo ntawm hluav taws xob thiab lub zog ntawm cov khoom raug them yog dab tsi?

Txoj cai. Coulomb txoj cai hais tias: Qhov loj ntawm cov electrostatic zog of attraction los yog repulsion nruab nrab ob point nqi yog ncaj proportional rau cov khoom ntawm qhov loj ntawm nqi thiab inversely proportional rau lub square ntawm qhov deb nruab nrab lawv. Cov zog yog raws txoj kab ncaj nraim koom nrog lawv.

Tus qauv rau hluav taws xob teb yog dab tsi?

qhov loj ntawm qhov hluav taws xob (E) tsim los ntawm ib qho taw tes nqi nrog a nqi ntawm qhov loj Q, ntawm qhov chaw nyob deb r deb ntawm qhov taw tes nqi , 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.
