Molao oa Newton oa matla a khoheli a bokahohleng - mathata le litharollo

1. Sebaka se pakeng tsa motho ea boima ba lik'hilograma tse 40 le motho ea boima ba lik'hilograma tse 30 ke limithara tse 2. Matla a khoheli ao e mong le e mong a a sebelisang ho e mong ke afe. ​​Bokahohle bo sa fetoheng = 6.67 x 10 ^-11 N m ² / kg ²

Tse tsejoang:

m ₁ = 40 kg, m ₂ = 30 kg, r = 2 m, G = 6.67 x 10 ^-11 N m ² / kg ²

Ho batloa: boholo ba matla a khoheli (F)?

2. Sebaka se pakeng tsa Lefatše le Khoeli (r) ke 3.84 x 10 ⁸ m. Matla a khoheli ao e 'ngoe le e 'ngoe e a sebelisang ho e 'ngoe ke afe?

Tse tsejoang:

Boima ba Lefatše (m _E ) = 5.97 x 10 ²⁴ kg

Boima ba Khoeli (m _M ) = 7.35 x 10 ²² kg

Sebaka se pakeng tsa setsi sa Lefatše le setsi sa Khoeli (r) = 3.84 x 10 ⁸ m

Sephetho sa bokahohleng (G) = 6.67 x 10 ^-11 N m ² / kg ²

Ho batloa: Boholo ba matla a khoheli (F)

Tharollo:

3. Sebaka se hokae ho tloha Lefatšeng, boholo ba matla a khoheli a lefatše le khoeli ke lefela?

Tse tsejoang:

Boima ba Lefatše = 5.97 x 10 ²⁴ kg

Boima ba Khoeli = 7.35 x ¹⁰²² kg

Sebaka se pakeng tsa setsi sa Lefatše le setsi sa Khoeli (r) = 3.84 x 10 ⁸ m.

Sephetho sa bokahohleng ( G) = 6.67 x 10 ^-11 N m ² / kg ²

Ho batloa: sebaka ho tloha Lefatšeng

Tharollo:

Matla a khoheli a net ke lefela.

Sebelisa foromo ea quadratic:

A = – 6.35

B = – 7.68 x 10 ⁸

C = 87.76 x 10 ^-14
