Answer:-
- Let the mass of first body be M and mass of second body be m.
Given:-
- Gravitational force between them = F.
We know that,
- Gravitational force (F) = GMm/r²
- [ where r is the Distance between them and G is the gravitational constant. ]
So,
⟶ F = GMm/r² -- equation (1)
Now,
- Their masses are halved.
- mass of first body = M/2
- mass of second body = m/2
Let ,
Gravitational force between them = F'
⟶ F' = G(M/2)(m/2) / r²
⟶ F' = (GMm/4) * 1/r²
⟶ F' = (GMm/r²) * (1/4)
⟶ F' = F * 1/4
[ from equation (1) ]
::⟶ F' = F/4
∴ The gravitational force between them reduces to F/4 when the masses of objects are halved.
