I-flux kagesi - izinkinga nezixazululo

1. Insimu kagesi efanayo E = 8000 N/C idlula endaweni eyisikwele eyisicaba A = 10 m2 ^. Thola ukugeleza kukagesi.

Kwaziwa:

Ubukhulu bensimu kagesi (E) = 8000 N/C

Indawo (A) = 10 m ²

θ = 0 ^o (i-engeli ephakathi kwesiqondiso sensimu kagesi kanye nomugqa odwetshwe uqonde endaweni)

Okufunwayo: Ugesi ogelezayo ( Φ)

Isixazululo:

Ifomula ye-flux kagesi:

Φ = EA cos q

Φ = ukugeleza kukagesi ( Nm ² /C) , E = insimu kagesi (N/C), A = indawo (m ² ), q = i-engeli phakathi komugqa wensimu kagesi nomugqa ojwayelekile.

Ukushintshashintsha kukagesi:

Φ = EA cos q = (8000)(10)( cos 0) = (8000)(10)(1 ) = 80,000 = 8 x 10 ⁴ Nm ² /C

2. Insimu kagesi efanayo E = 5000 N/C idlula endaweni yesikwele esiyisicaba A = 2 m 2. ^Thola ukugeleza kukagesi.

Kwaziwa:

Insimu kagesi (E) = 5000 N/C

Indawo (A) = 2 m ²

θ = 60 ^o (i-engeli ephakathi kwesiqondiso sensimu kagesi kanye nomugqa odwetshwe uqonde endaweni)

Okufunwayo: Ugesi ogelezayo ( Φ)

Isixazululo:

Ukushintshashintsha kukagesi:

Φ = EA cos q = (5000)(2)( cos 60) = (5000)(2)(0.5 ) = 5000 = 5 x 10 ³ Nm ² /C

3. Ibhola eliqinile elinobubanzi obungamamitha angu-0.5 lineshaja kagesi engu-10 μC phakathi nendawo. Thola ukugeleza kukagesi okudlula ebholeni eliqinile.

Kwaziwa:

Irediyasi yebhola (r) = 0.5 m

Ishaja kagesi (Q) = 10 μC = 10 x 10 ^-6 C

Okufunwayo: Ugesi ogelezayo ( Φ)

Isixazululo:

Insimu kagesi:

E = kq/r ²

E = (9 x 10 ⁹ Nm ² /C ² ) ( 10 x 10 ^-6 C) / 0.5 ²

E = (90 x 10 ³ ) / 0,25

E = 360 x 10 ³

E = 3.60 x 10 ⁵ N/C

Indawo engaphezulu:

A = 4 π r ² = 4 (3.14) (0.5) ² = (12.56) (0.25) = 3.14 m ²

Ukushintshashintsha kukagesi:

Imigqa yensimu kagesi iqonde ngqo endaweni, ukuze i-engeli ephakathi kwesiqondiso sensimu kagesi kanye nomugqa odwetshwe uqonde ngqo endaweni, ibe ngu -0 ^o.

Φ = EA cos q

Φ = ( 3.60 x 10 ⁵ )( 3.14 )( cos 0)

Φ = (11.304 x 10 ⁵ )(1)

Φ = 11.304 x 10 ⁵

Φ = 1.13 x 10 ⁶ Nm ² /C
