Two bodies of equal masses are some distance apart. If \(20 \%\) of mass is transferred from the first body to the second body, then the gravitational force between them
- A increase by \(4 \%\)
- B increase by \(14 \%\)
- C decreases by \(4 \%\)
- D decreases by \(14 \%\)
Answer & Solution
Correct Answer
(C) decreases by \(4 \%\)
Step-by-step Solution
Detailed explanation
(c) Initially force, \[ F_1=\frac{G m^2}{r^2} \] When \(20 \%\) mass is transferred from one body to another, then their masses are \[ m_1=\frac{80}{100} m \text { and } m_2=\frac{120}{100} m \] So, force is finally \[ F_2=\frac{G m^2}{r^2} \times\left(\frac{24}{25}\right) \]…
