Two balls, each of radius R, equal mass and density are placed in contact, then the force of gravitation between them is proportional toA. `F prop(1)/(R^(2))`B. `F prop R`C. `F propR^(4)`D. `F prop (1)/(R)` |

Answer» Correct Answer - 3 `F = (GM^(2))/((2R)^(2))` `M=(4)/(3) piR^(3)rho` `F prop (M^(2))/(R^(2))` `F prop (R^(6))/(R^(2))` `R prop R^(4)` |
