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.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov kev sib raug zoo ntawm cov kab hluav taws xob thiab cov chaw equipotential?
Equipotential kab yog ib txwm perpendicular mus rau hluav taws xob teb. Nyob rau hauv peb qhov ntev, cov kab tsim equipotential nto. Kev txav mus los ntawm qhov chaw anequipotential yuav tsum tsis txhob ua haujlwm vim tias qhov kev txav no ib txwm nyob rau ntawm qhov chaw hluav taws xob
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
