Question

The force of attraction between two objects of masses 2m amd m is F₁.When the object with mass 2m is replaced with another object of mass m/2 ,the new force of attraction is found to be F₂.The ratio of F₁:F₂ IS:- (A)3:2 (B)2:3 (C)1:4 (D)=4:1 ⇒SPAMMER ARE REQUESTED TO STAY AWAY ⇒Need detailed answer from physics newton and other best user :)​

Answer 1

Explanation:

For the 2nd case :

We have :

→ 1st mass = m/2

→ 2nd mass = m

→ Gravitational force = F2

→ Distance between the masses = r

Vol 85

Again by the law of Gravitation, we have the 2nd equation as :

F₂ = (G x m/2 x m)/r²

F₂ = (Gm²/2)/r²

→ F₂ = Gm²/2r²

-(2)

On dividing eq.1 by eq.2, we get :

F₁/F₂ = (2Gm²/r²) + (Gm²/2r²)

F₁1/F₂ = 2Gm²/r² x 2r²/Gm²

F₁/F₂ = (2 x 2)/1

F₁1/F₂ = 4/1

F₁: F₂ = 4:1
