Dardargelinta cufisjiidadka awgeed - dhibaatooyinka iyo xalalka

1. Waa maxay dardargelinta cufisjiidadka dusha sare ee Dayaxa? Cufka Dayaxa = 7.35 x 10 ²² kg, gacanka Dayaxa waa 1.7 x 10 ⁶ m, joogto caalami ah waa 6.67 x 10 ^-11 N m ² / kg ²

Solution

Qaacidda sharciga labaad ee dhaqdhaqaaqa Newton :

Qaacidada sharciga cufisjiidadka guud ee Newton :

G = joogto caalami ah, M = Cufnaanta Dhulka, m = Cufnaanta Shayga, r = masaafada u dhaxaysa bartamaha Dhulka iyo shayga. Haddii shaygu uu ku yaal dusha sare ee Dhulka, r = Gacanka Dhulka

Ku beddel F ee isla'egta 1 iyo F ee isla'egta 2:

Waa maxay dardargelinta cufisjiidadka oo ka dhasha dusha sare ee Dayaxa?

2. Dardargelinta cufisjiidadka dhulka dushiisa waa g. R (R waa dusha sare ee dhulka), dardargelinta cufisjiidadka awgeed waa…

Solution

R = Gacanka Dhulka. R oo ka sarreeya dusha sare ee Dhulka = 2R oo ka sarreeya bartamaha Dhulka.

Marka R ka sarreeyo dusha sare ee Dhulka, dardargelinta cufisjiidadka awgeed = ¼ g. Haddii g = 9.8 m/s ² , marka R ka sarreysa dusha sare ee Dhulka, dardargelinta cufisjiidadka awgeed = 2.45 m/s ².
