Forces and Inertia :: Discussion
| 7. | A body of mass 2kg is placed on a rough horizontal plane. The coefficient of friction between body and the plane is 0.2. Then ? | |
| A. | Body will move in forward direction if F=3N | |
| B. | Body will move in backward direction with acceleration of 0.5m/s2, if force F=3N | |
| C. | If F=3N, then body will be in rest condition | |
| D. | The body will move both in forward during a particular period and then remain at rest | |
| Answer: Option D | |
| Explanation: | |
|
Limiting friction, f = μR = μmg = 0.2×2×9.8=3.92N |
