Izinhlobo zamacala kagesi - izinkinga nezixazululo
1. Ngokusekelwe esifanekisweni samanani kagesi angezansi.
Izinto A no-D zishajwa kabi (-), into A idonsela into B futhi ixosha into C, into D ixosha u -E. Nquma uhlobo lweshaja kagesi yezinto B, C, no-E.
A. Okuhle, Okuhle, Okubi
B. Okubi, Okubi, Okuhle
C. Okuhle, Okubi, Okubi
D. Okuhle, Okubi, Okuhle
Isixazululo:
Ishaja kagesi inezinhlobo ezimbili: ishaja kagesi elungile kanye neshaja kagesi engalungile . Uhlobo ngalunye lweshaja luyaxosha uhlobo olufanayo kodwa ludonsela uhlobo oluphambene. Okungukuthi: ngokungafani namacala ayadonsa; njengamacala ayaxosha.
Uma ishaja u-A iyishaja elungile, ishaja u-A ixosha ishaja u-B, khona-ke ishaja u-B iyishaja elungile. Uma ishaja u-P iyishaja elungile, ishaja u-P idonsela ishaja u-Q, khona-ke ishaja u-Q iyishaja elungile.
I-A iyinkokhelo engemihle.
I-D iyinkokhelo engemihle.
U-A udonsela u-B ukuze u-B abe yi-positive charge.
U-A uxosha u-C ukuze u-C abe yi-negative charge.
U-D uxosha u-E ukuze u-E abe yi-negative charge.
Izinhlobo zezindleko B, C, kanye no-E zinhle, zimbi, zimbi.
Impendulo efanele ithi C.

Uma ingilazi ihlikihlwa ngesilika, incazelo efanele kuthebula elilandelayo ithi …
Isixazululo
Ingilazi ineshaja enhle, ngakho-ke uma ingilazi ihlikihlwa ngendwangu yesilika khona-ke ama-electron asuka engilazini aye kusilika, ngakho ingilazi inama-proton amaningi kunama-electron.
Ama-proton ashajwa kahle ngakho-ke ingilazi ishajwa kahle. Esikhundleni salokho, isilika inama-electron amaningi kunama-proton. Ama-electron ashajwa kabi ukuze indwangu yesilika ishajwe kabi.
Impendulo eyiyo ngu-A.

3. Induku yepulasitiki ehlikihlwe ngoboya , incazelo efanele ithi… ..
A. Ama-electron eboyeni aya epulasitikini, ipulasitiki ishajeke kabi
B. Ama-electron epulasitiki aya eboyeni, uboya bushajwa kabi
C. Ama-electron kuboya ayashintshana abe yipulasitiki nama-proton, uboya bushajwa kabi
D. Ama-electron epulasitikini aya kuboya futhi ashintshane nama-proton, amapulasitiki ashajwa kahle
Isixazululo:
TIshaja kagesi kumapulasitiki kuvunyelwene ngayo emhlabeni wonke njengeshaja engemihle.
Ipulasitiki noma noma iyiphi into iba ne-negative charge ngenxa yama-electron amaningi. Ngenxa yokuthi ipulasitiki ihlikihlwa ngoboya, kuphethwa ngokuthi ama-electron asuka kuboya aye kupulasitiki.
Impendulo eyiyo ngu-A.
4. Kukhona umqhubi we-ball P one-negative charge kanye namabhola amane e-Q, R, S, T.
U-B wonke u-P udonsela u-Q futhi uxosha u-S. Ibhola u-Q uxosha u-R kanti ibhola u-S uxosha u-T. Uma ibhola u-P lisondezwa eduze kwebhola u-R kanye nebhola u-T khona-ke…..
Isixazululo
U-P uheha u -Q ukuze u-Q abe yi-positive charge
U-P uxosha u -S ukuze u-S abe yi-negative charge
U-Q uxosha u-R ukuze u-R abe yi-positive charge
U-S uxosha u-T ukuze u-T abe yi-negative charge
Uma ibhola u- P lisondela ebholeni u- R khona-ke liyakhangana.
Uma ibhola u-P lisondela ebholeni u-T, bayaxoshana.
Impendulo efanele ngu- D.
