Two identical spheres each of mass M and radius R are separated by a distance 3R. The force of attraction between them is proportional toA. `(1)/(R^(2))`B. `R^(4)`C. `R^(2)`D. `(1)/(R^(4))` |
|
Answer» Correct Answer - B `F=(GM_(1)M_(2))/(d^(2))=(G[(4)/(3)pi R^(3)xx d][(4)/(3)pi R^(3)]d)/((3R)^(2))` i.e., `F prop (R^(6))/(R^(2))` or `F prop R^(4)` |
