Charles-Augustin de Coulomb, (yug Lub Rau Hli 14, 1736, Angoulême, Fabkis-tuag Lub Yim Hli 23, 1806, Paris), Fabkis tus kws kho mob paub zoo tshaj plaws rau kev tsim ntawm Coulomb's txoj cai lij choj, uas tau hais tias lub zog ntawm ob tus nqi hluav taws xob yog proportional rau cov khoom ntawm cov nqi thiab inversely proportional rau lub square ntawm lub …
Coulomb nrhiav tau nws li cas?
Coulomb qhov tas li tau tshawb pom thiab muaj npe tom qab Charles-Augustin de Coulomb. Nws txiav txim siab lub zog ntawm lub zog hluav taws xob los ntawm kev ntsuas lub zog ntawm cov khoom siv hluav taws xob uas siv lub torsion tshuavTsis muaj ib yam dab tsi los txiav txim, thiab kuv tsis tau hnov tias qhov tas li no muaj npe tom qab Coulomb.
Q txhais li cas hauv physics?
q yog lub cim siv los sawv cev charge , thaum n yog tus lej zoo lossis tsis zoo, thiab e yog tus nqi hluav taws xob, 1.60 x 10 - 19 Coulombs.
Q1 thiab q2 yog dab tsi hauv Coulomb txoj cai?
Coulomb's Law piav txog lub zog ntawm ob lub ntsiab lus zoo li tus nqi: q1q2 F=k---------- r^2 qhov twg k=Coulomb qhov tsis tu ncua=8.99 x 10^9 (Nm^2 / C^2) q1=them rau thawj particle (Coulombs) q2=them rau qhov thib ob particle (Coulombs) r=nrug ntawm cov khoom (meters)
Vim li cas Coulomb txoj cai tseem ceeb?
Nws txhais tau hais tias, qhov sib txawv ntawm qhov sib npaug ntawm lub zog hluav taws xob. Nws kuj tseem siv tau los muab cov txiaj ntsig yooj yim ntawm Gauss txoj cai lij choj rau cov teeb meem dav dav kom raug. Thaum kawg, daim ntawv vector ntawm Coulomb txoj cai tseem ceeb raws li nws pab peb qhia cov kev taw qhia ntawm hluav taws xob vim raug nqi
