7. Ibanga phakathi kwezingcezu ezimbili zensimbi ezihambisanayo lingu-0,2 cm. Izingcezu ezimbili zensimbi zinikezwa amacala kagesi aphambene kuze kube yilapho umehluko ongaba khona ufinyelela kuma-volts angu-20.000. I-electron charge ingu-1,6 × 10 –19 C. Ubukhulu kanye nesiqondiso samandla e-Coulomb ku-electron ephakathi kwezingcezu ezimbili zensimbi...
A. 0,80 × 10-12 N, phezulu

C. 1,20 × 10-12 N, phezulu
D. 1,62 × 10-12 N, phansi
E. 1,62 × 10-12 N, phezulu
Ingxoxo:
I-Diketahui :
d = 0,2 cm = 0,002 m
V = 20.000 Volt
e = 1,62 x 10-19 C
Kubuziwe :
Amandla kagesi (F) ?
Jawab :
Ifomula yensimu kagesi, i-voltage kanye nebanga phakathi kwamapuleti :
E = V / d
Incazelo: E = insimu kagesi, V = i-voltage, d = ibanga phakathi kwamapuleti
Ifomula yamandla e-Coulomb, insimu kagesi kanye nokushaja :
F = q E
Incazelo: F = Amandla e-Coulomb noma amandla kagesi, q = ukushaja, E = insimu kagesi
Ubukhulu kanye nesiqondiso samandla e-Coulomb kuma-electron :
F = q E = q V / d
F = (1,62 x 10-19 C(20.000 V) / 0,002 m
F = 1,62 x 10-12 N
Ama-electron ashajwa kabi, ngakho-ke ayaxoshwa yipuleti elibi futhi akhangwe yipuleti elihle. Ngakho-ke isiqondiso samandla siphezulu.
Impendulo efanele ngu-E.
