| A. | F= Gm1m2/r2 |
| B. | F= Gm1m2 |
| C. | F= m1m2/r2 |
| D. | F= Gm1m2/r3 |
| Answer» A. F= Gm1m2/r2 | |
| Explanation: Gravitational force was derived by Newton’s theory of gravitation. It is defined as the product of mass and acceleration due to gravity of the fluid flow. It is mainly present in cases of open surface fluid flow. | |
