Coulomb cov txoj cai hais tias: Qhov loj ntawm lub electrostatic zog ntawm attraction los yog repulsion ntawm ob lub ntsiab lus tsub nqi yog ncaj qha proportional rau cov khoom ntawm qhov loj ntawm cov nqi thiab inversely proportional rau lub square ntawm qhov kev ncua deb ntawm lawv. Cov zog yog raws txoj kab ncaj nraim koom nrog lawv.

Xav txog qhov no, dab tsi txiav txim siab qhov kev taw qhia ntawm lub zog hluav taws xob ntawm ob qhov nqi?

Cov kev taw qhia ntawm lub zog hluav taws xob yog nyob ntawm seb tus raug them cov khoom yog raug them nrog zoo li nqi los yog opposite nqi thiab raws li lawv spatial orientation. Los ntawm kev paub txog hom nqi ntawm ob objects, cov kev taw qhia ntawm zog ntawm ib qho ntawm lawv tuaj yeem ua tau txiav txim siab nrog me ntsis kev xav.

Qhov thib ob, lub ntsiab txhais ntawm ib tug Coulomb yog dab tsi? coulomb . npe. Abbr. C. Lub hauv paus ntawm cov nqi hluav taws xob, sib npaug ntawm cov nqi xa mus rau hauv ib thib ob los ntawm qhov tsis tu ncua ntawm ib ampere, thiab sib npaug rau 6.2415 × 1018 pib nqi, qhov twg ib elementary charge yog tus nqi ntawm ib tug proton los yog qhov tsis zoo ntawm tus nqi ntawm electron.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov kev taw qhia ntawm hluav taws xob teb ntawm lub hauv paus chiv keeb?

Vim lub hluav taws xob teb los ntawm tus nqi tsis zoo ntsiab lus radially mus rau qhov tsis zoo. Hauv lwm lo lus, lub hluav taws xob teb tsim los ntawm tus nqi tsis zoo ntawm qee qhov chaw nyob ib puag ncig nws yuav taw tes rau tus nqi tsis zoo tsim qhov ntawd hluav taws xob teb.

Koj xam qhov loj ntawm lub zog li cas?

Cov qhov loj ntawm net zog ua yeeb yam ntawm ib yam khoom yog sib npaug rau qhov loj ntawm cov khoom sib npaug los ntawm qhov acceleration ntawm cov khoom raws li qhia hauv cov qauv hauv qab no.
