Ukuhanjiswa kokushisa - izinkinga nezixazululo

1. Izinsimbi ezimbili zinobukhulu obufanayo kodwa zinezinhlobo ezahlukene. Ukuqhuba ukushisa kwe-P = izikhathi eziphindwe kabili kunokuqhuba ukushisa kwe-Q. Kuyini lokushisa phakathi kwezinsimbi ezimbili, njengoba kuboniswe esithombeni esingezansi.

Kwaziwa:

k_Q = k

k_P = 2k

Okufunayo: Izinga lokushisa phakathi kwezinsimbi ezimbili

I-Torque

1. Umshayo onobude obuyi-140 cm. Kunezenzo ezintathu zamandla emshayo, F₁ = 20 N, F₂ = 10 N, kanye no-F₃ = 40 N ngesiqondiso nendawo njengoba kuboniswe esithombeni esingezansi. Kuyini itorque kubangela ukuthi ugongolo lujikeleze phakathi nendawo yobunzima bogongolo?

Kwaziwa:

Isikhungo sesisindo sitholakala enkabeni ye-beam.

Amasimu kagesi - izinkinga nezixazululo

1. Iphuzu A litholakala phakathi kwamashaji amabili. Womabili amashaji anobukhulu obufanayo kodwa uphawu oluphambene futhi ahlukaniswe yibanga elingu-a. Ubukhulu bensimu kagesi endaweni A bungu-36 N/C. Uma iphuzu A lihamba u-1/2a eduze kwenye yazo zombili imithwalo, ubukhulu be- inkambu kagesi ephuzwini A?

Kwaziwa:

Shaja 1 (q₁) = +Q

Shaja 2 (q₂) = -Q

Ibanga eliphakathi kokushaja 1 nephuzu A (r_1A) = ½ a

Amandla kagesi - izinkinga nezixazululo

1. Three imithwalo njengoba kuboniswe esithombeni esingezansi. Kuyini amandla kagesi obhekene no-B. k = 9x10⁹ Nm²C^-2, 1 μC = 10^-6 C.

Kwaziwa:

q_A = 10 µC = 10 x 10^-6 C=10^-5 I-Coulomb

q_B = 10 µC = 10 x 10^-6 = 10^-5 I-Coulomb

q_C = 20 µC = 20 x 10^-6 = 2 x10^-5 I-Coulomb

Amandla kagesi

1. Iphuzu A ku- inkambu kagesiUbukhulu bensimu kagesi endaweni A = 0.5 NC^-1Uma ishaja engu-0.25-C ibekwe endaweni A, pho iyini amandla kagesi okwenziwa ngecala.

Kwaziwa:

Insimu kagesi endaweni A = 0.5 NC^-1

imali kagesi endaweni A = 0.25 C

Okufunayo: Amandla kagesi
