1-NAZORAT ISHI
Nazorat shakli: Fizik diktant
Bir xil ishorada zaryadlangan jismlar . . , turli xil ishorada zaryadlangan jismlar . . Elektr o’tkazmaydigan modda va jismlar . . . . deb ataladi. Dielektriklardan yasalgan jismlarga . . .deyiladi.
Zaryadlar jism . . . taqsimlanadi. Uchlik joylarida . . . , tekis joylarida . . . bo’ladi.
Kulon qonuni. Ikkita nuqtaviy elektr zaryadlarining o’zaro ta’sir kuchi, shu zaryadlarning miqdorlariga . . . va orasidagi masofaning kvadratiga . . . manfiy zaryadniki esa zaryadga . . . bo’ladi.
Javoblar: tortishadi, teskari proporsional, tekis, sirtida, Dielektriklar, izolyatorlar, siyrak, teng, to’g’ri proporsional, Itarilishadi,
