Kuyerera kwemagetsi - matambudziko nemhinduro

1. Munda wemagetsi wakaenzana E = 8000 N/C unopfuura nepakati penzvimbo yakati sandara ine sikweya A = 10 m2 ^. Tsvaga kuti magetsi ari kufamba sei.

Zvinozivikanwa:

Hukuru hwesimba remagetsi (E) = 8000 N/C

Nzvimbo (A) = 10 m ²

θ = 0 ^o (kona iri pakati pegwara remagetsi nemutsetse wakadhirowewa wakatarisana nenzvimbo yacho)

Zvinodiwa: Kuyerera kwemagetsi ( Φ)

Solution:

Fomura yemagetsi ekufambisa:

Φ = EA cos q

Φ = flux yemagetsi ( Nm ² /C) , E = munda wemagetsi (N/C), A = nzvimbo (m ² ), q = kona iri pakati pemutsetse wemagetsi nemutsetse wakajairika.

Kuyerera kwemagetsi:

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

2. Munda wemagetsi wakaenzana E = 5000 N/C unopfuura nepakati penzvimbo yakati sandara ine sikweya A = 2 m ^2. Tsvaga kuti magetsi ari kufamba sei.

Zvinozivikanwa:

Munda wemagetsi (E) = 5000 N/C

Nzvimbo (A) = 2 m ²

θ = 60 ^o (kona iri pakati pegwara remagetsi nemutsetse wakadhirowewa wakatarisana nenzvimbo yacho)

Zvinodiwa: Kuyerera kwemagetsi ( Φ)

Solution:

Kuyerera kwemagetsi:

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

3. Bhora rakasimba rine 0.5 metres radius rine 10 μC electric charge pakati paro. Tsvaga kuti flux yemagetsi inopfuura nepabhora rakasimba.

Zvinozivikanwa:

Nharaunda yebhora (r) = 0.5 m

Chaja yemagetsi (Q) = 10 μC = 10 x 10 ^-6 C

Zvinodiwa: Kuyerera kwemagetsi ( Φ)

Solution:

Munda wemagetsi:

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

Nzvimbo yepamusoro:

A = 4 π r ² = 4 (3.14) (0.5) ² = (12.56) (0.25) = 3.14 ^m2

Kuyerera kwemagetsi:

Mitsetse yemagetsi yakatarisana nenzvimbo, zvekuti kona iri pakati pegwara remagetsi nemutsetse wakadhonzwa wakatarisana nenzvimbo, i0 ^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
