Coulomb txoj cai hais tias: Qhov loj ntawm lub electrostatic quab yuam ntawm attraction los yog repulsion ntawm ob lub ntsiab lus 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. Lub zog yog raws txoj kab ncaj nraim koom nrog lawv.

Hais txog qhov no, vim li cas Coulomb txoj cai tseem ceeb?

Nws txhais tau hais tias, qhov rov qab square dependence ntawm hluav taws xob quab yuam. Nws kuj tseem siv tau los muab cov txiaj ntsig yooj yim ntawm Gauss ' txoj cai rau cov xwm txheej dav dav kom raug. Thaum kawg, daim ntawv vector ntawm Coulomb txoj cai yog tseem ceeb raws li nws pab peb qhia cov kev taw qhia ntawm hluav taws xob teb vim raug nqi.

Tsis tas li, q1 thiab q2 yog dab tsi hauv Coulomb txoj cai? Coulomb txoj cai hais tias lub zog F ntawm ob lub ntsiab lus them nqi Q1 thiab Q2 yog: Raws li txoj kab koom nrog lawv. Ncaj nraim propotional rau cov khoom Q1Q2 ntawm cov nqi. inversely propotional rau lub square ntawm qhov kev ncua deb R ntawm lawv.

Tsis tas li ntawd, Q hauv Coulomb txoj cai sawv cev rau dab tsi?

Coulomb Txoj Cai Kev sib npaug qhov twg Q ₁ sawv cev kom muaj nuj nqis ntawm cov khoom 1 (hauv Coulombs ), Q ₂ sawv cev kom muaj nuj nqis ntawm cov khoom 2 (hauv Coulombs ), thiab d sawv cev qhov kev ncua deb ntawm kev sib cais ntawm ob yam khoom (hauv meters). Lub cim k yog proportionality tas li hu ua tus Coulomb txoj cai tas li.

Koj txhais li cas tus nqi?

Hauv physics, nqi , tseem hu ua hluav taws xob nqi , hluav taws xob nqi , los yog electrostatic nqi thiab cim q, yog ib tug yam ntxwv ntawm ib chav tsev ntawm cov teeb meem uas qhia txog qhov uas nws muaj ntau dua los yog tsawg dua electrons tshaj protons.
