JEE Main 2022 (Online) 28th June Evening Shift Physics - Gravitation Question 93 English Explanation

Let the masses are m and distance between them is l, then F=Gm2l2F = {{G{m^2}} \over {{l^2}}} .

When 1/3rd mass is transferred to the other then masses will be 4m3{{4m} \over 3} and 2m3{{2m} \over 3} . so new force will be

F′=G4m3×2m3l2=89Gm2l2=89FF' = {{G{{4m} \over 3} \times {{2m} \over 3}} \over {{l^2}}} = {8 \over 9}{{G{m^2}} \over {{l^2}}} = {8 \over 9}F
