Ib electroscope yog ib qho cuab yeej uas kuaj xyuas cov hluav taws xob zoo li qub los ntawm kev siv cov hlau nyias lossis cov nplooj yas, uas cais thaum raug them . Hluav taws xob nqi txav mus rau lub metaland nqes mus rau cov ntawv ci nplooj, uas ces sib ntaus sib tua. Sinceeach nplooj muaj tib yam nqi (zoo lossis tsis zoo), lawv sib cav sib ceg.

Raws li txoj cai, koj puas tuaj yeem qhia tau yog tias ib qho khoom muaj qhov zoo lossis tsis zoo nrog lub Electroscope?

Yog koj nqa a yam tsis zoo nyob ze ntawm electroscope , cov electrons nyob rau hauv lub Scope yuav berepelled rau nplooj, sib npaug ntawm nqi . Yog koj nqa a yam khoom zoo nyob ze ntawm electroscope , nws yuav nyiam cov electrons mus rau lub davhlau ya nyob twg. Nplooj yuav txav deb ntawm ib leeg.

Ib sab saum toj no, koj tuaj yeem siv lub pob pith Electroscope li cas los txiav txim qhov muaj nqi? Qhov no pith - pob electroscope yog siv rau ntes lub xub ntiag ntawm ib qho hluav taws xob static nqi . Ob lub teeb pith ” pob tshem tawm los ntawm cov hlua yog attracted rau cov khoom nrog ib tug staticelectric nqi . Cov pith pob tuaj yeem yog raug them los ntawm kev kov lawv rau ib yam khoom uas muaj hluav taws xob zoo li qub nqi.

Ib yam li ntawd, koj yuav paub li cas yog tias ib qho khoom raug them?

Nyob rau hauv thiaj li yuav qhia sign ib khoom nqi , koj xav tau lwm tus khoom nrog tus paub zoo ornegative nqi . Yog koj rub ib daim iav nrogsilk, nws yuav muaj qhov zoo nqi (los ntawm convention). Yog koj rub ib daig ntawm amber nrog plaub, nws yuav muaj anegative nqi (tseem los ntawm kev sib tham). Siv txhua yam uas koj muaj.

Puas yog Electroscope cuam tshuam tsis zoo?

Yog li ntawd, thaum lub sij hawm tsis zoo - raug them qws isbrought close, the electroscope tau txais txiaj ntsig zoo nqi raws li ib co ntawm nws cov electrons tau khiav mus rau hauv kuv tus ntiv tes. Qhov saum toj kawg nkaus, uas yog nyob ze rau ntawm tsis zoo - raug them rod yog raug them , tab sis qhov qis dua ntawm cov electroscope nyob nruab nrab.
