Equipotential kab ntawm qhov sib txawv muaj peev xwm yeej tsis tau ntoo khaub lig los yog. Qhov no yog vim lawv, los ntawm kev txhais, a kab ntawm qhov muaj peev xwm tas mus li. Cov equipotential ntawm ib qho chaw hauv qhov chaw tuaj yeem tsuas muaj ib tus nqi xwb. Lus Cim: Nws yog ua tau rau ob kab sawv cev tib lub peev xwm rau ntoo khaub lig.
Xav txog qhov no, nws puas ua tau rau ob txoj kab sib txawv lossis ob txoj kab hluav taws xob los hla kev piav qhia?
Nws tsis yog ua tau rau ob txoj kab sib txawv equipotential lossis ob txoj kab hluav taws xob los hla vim equipotential kab muaj qhov tseem ceeb ntawm kev txhais. Yog lawv yuav ntoo khaub lig ces nws yuav tsim ob txawv qhov tseem ceeb uas tsis muaj qab hau.
Kuj Paub, ob kab hluav taws xob tuaj yeem cuam tshuam ib leeg? Cov kab hluav taws xob ib txwm taw tes rau hauv ib qho kev taw qhia, ntawm txhua qhov chaw. Thaum twg ob kab sib tshuam , tangents yog kos rau ntawm qhov taw tes qhia ob cov lus qhia ntawm hluav taws xob teb kab , uas yog tsis yooj yim sua hluav taws xob teb kab ua tsis tau ntoo khaub lig dhau ib leeg.
Tsis tas li ntawd, cov kab hluav taws xob hauv hluav taws xob cuam tshuam li cas rau cov kab hluav taws xob equipotential lawv hla ib leeg li cas?
Cov kab hluav taws xob los ntawm ib qho kev them nqi ib txwm ntoo khaub lig qhov no equipotential nto perpendicular rau saum npoo no. Yog li ntawd yog tias koj muaj qhov zoo taw tes them nqi, qhov twg hluav taws xob teb kab yog radiating sab nraud, lub equipotential nto nyob ib ncig ntawm tus nqi no yog spherical.
Vim li cas hluav taws xob tsis tuaj yeem hla ib leeg?
Hluav taws xob kab zog yeej tsis kev sib tshuam vim nyob rau hauv lub point ntawm kev sib tshuam, ob tangents ua tau tau kos rau ob kab ntawm lub zog. Qhov no txhais tau tias ob txoj kev ntawm hluav taws xob teb ntawm qhov chaw ntawm kev sib tshuam, uas tsis yog ua tau.

Cov kab hluav taws xob ua li cas qhia tias hluav taws xob muaj zog?
Lub zog ntawm cov hluav taws xob hluav taws xob nyob ntawm qhov chaw them nqi, tsis yog ntawm qhov kev xeem nqi. Ib kab tangent mus rau ib kab teb qhia txog kev taw qhia ntawm hluav taws xob ntawm qhov taw tes. Qhov twg cov kab teb nyob ze ua ke, cov hluav taws xob hluav taws xob muaj zog dua qhov uas lawv nyob deb
Puas yog nws ua tau rau ob qhov chaw equipotential hla kev piav qhia?
Equipotential kab ntawm cov peev txheej sib txawv tuaj yeem tsis hla ib qho. Qhov no yog vim hais tias lawv yog, los ntawm kev txhais, ib txoj kab ntawm lub peev xwm tas li. Lub equipotential ntawm ib qho chaw hauv qhov chaw tuaj yeem tsuas muaj ib qho nqi xwb. Lus Cim: Nws yog ua tau rau ob kab sawv cev tib lub peev xwm hla
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
Vim li cas cov kab hluav taws xob ua hluav taws xob yog perpendicular rau equipotential nto?
Txij li cov kab hluav taws xob hluav taws xob taw qhia radiallyaway ntawm tus nqi, lawv yog perpendicular mus rau cov kab hluav taws xob. Lub peev xwm yog tib yam nyob rau hauv txhua txoj kab uas muaj peev xwm, txhais tau hais tias tsis muaj haujlwm yuav tsum tau txav mus los ntawm ib qho ntawm cov kab no
