Question

Oblicz natężenie w punkcie C pola.

Answer 1

 

Ra= r

Rb= 0,5 r 

Ma= 4m

Mb= m

Mc

 

γ (b) = G MaMb/Ra^2 / Mb =  G Ma/Ra^2

γ (c) = G McMb/Rb^2 / Mc =  G Mb/Rb^2

γ (b) / γ (c) = G Ma/Ra^2   /    G Mb/Rb^2

γ (b) / γ (c) = 4m/r^2   /    m/(0,5r)^2

γ (b) / γ (c) = 4/r^2   / 4/r^2

γ (b) / γ (c)= 1 
γ (b) = γ (c)
