Txoj cai. Coulomb txoj cai hais tias: Qhov loj ntawm electrostatic zog ntawm attraction los yog repulsion nruab nrab ntawm ob taw tes nqi yog ncaj qha 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.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog ob txoj hauv kev uas lub zog hluav taws xob ntawm ob qho khoom them tuaj yeem nce ntxiv?
Hauv electrostatics, lub hluav taws xob quab yuam ntawm ob yam khoom uas them yog inversely cuam tshuam rau qhov kev ncua deb ntawm kev sib cais nruab nrab tus ob yam khoom . Kev nce ntxiv kev sib cais nrug nruab nrab ntawm cov khoom txo cov zog ntawm attraction los yog repulsion nruab nrab tus khoom.
Tsis tas li ntawd, dab tsi yog lub zog ntawm cov khoom siv hluav taws xob? Coulomb Force -- los ntawm Eric Weisstein's World of Physics. Cov Coulomb zog nruab nrab ob lossis ntau dua raug them lub cev yog cov zog nruab nrab lawv vim Coulomb cov txoj cai. Yog tias cov khoom yog ob qho tib si zoo los yog tsis zoo raug them , cov zog yog khib; yog hais tias lawv yog opposite nqi , nws yog txaus nyiam.
Tib neeg kuj nug, thaum qhov kev ncua deb ntawm ob yam khoom raug them ob npaug li cas lub zog ntawm lawv?
Qhov loj ntawm tus zog nws txawv inversely raws li lub square ntawm tus nrug ntawm tus ob nqi . Yog li ntawd, yog hais tias tus nrug ntawm tus ob nqi yog ua ob npaug , qhov attraction los yog repulsion yuav qaug zog, txo rau ib- plaub ntawm tus nqi qub.
Yam dab tsi cuam tshuam rau lub zog hluav taws xob muaj zog npaum li cas ntawm ob yam khoom siv?
Lub npe ob yam uas cuam tshuam rau lub zog ntawm lub zog hluav taws xob, thiab piav qhia seb lawv cuam tshuam li cas. Thawj qhov tseem ceeb yog tus nqi ntawm txhua yam khoom. Tus nqi ntau dua, lub zog hluav taws xob ntau dua. Qhov thib ob yam yog qhov nyob deb nruab nrab ntawm cov nqi.

Yuav ua li cas hom ntawm cov khoom raug txheeb xyuas los ntawm nws lub cev thiab tshuaj lom neeg lub zog?
Intensive zog, xws li ceev thiab xim, tsis nyob ntawm seb tus nqi ntawm cov khoom tam sim no. Lub cev lub cev tuaj yeem ntsuas yam tsis tau hloov cov khoom siv tshuaj lom neeg. Cov khoom siv tshuaj muaj peev xwm ntsuas tau los ntawm kev hloov cov tshuaj lom neeg tus kheej
Dab tsi yog them los ntawm rubbing thiab them los ntawm induction?
Friction charging yog ib txoj hauv kev zoo tshaj plaws ntawm kev them cov khoom. Induction charging yog ib txoj kev siv los them cov khoom yam tsis tau kov cov khoom mus rau lwm yam khoom siv
Dab tsi yog ob txoj hauv kev uas lub zog hluav taws xob ntawm ob qho khoom them tuaj yeem nce ntxiv?
Nyob rau hauv electrostatics, hluav taws xob quab yuam ntawm ob yam khoom them yog inversely cuam tshuam rau qhov kev ncua deb ntawm kev sib cais ntawm ob yam khoom. Ua kom qhov kev sib cais deb ntawm cov khoom txo qis lub zog ntawm kev nyiam los yog kev tawm tsam ntawm cov khoom
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
