Question

Gravitational attraction on Earth on the stone of mass $M$ is$F_S$. If the force on the hydrogen balloon of mass $M$ located at the same space is $F_B$, then

• A. $F_S>F_B$
• B. $F_S<F_B$
• C. $F_s=F_B$
• D. $F_S=-F_B$

Answer 1

The correct option is C

$F_s=F_B$

Gravitational force

1. The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.
   $F=\frac{GmM}{r^2}$
   Where $G$is gravitational constant,$m$ mass of the first object, in $kg$, $M$ mass of the second object, in$kg$ and $R$distance between objects, in$m$
2. According to the question, the two bodies are experiencing the gravitational pull due to Earth and having the same mass and height from the earth, so the gravitational force will be the same on both the bodies.

Hence option C is correct
