A block of unknown mass is at rest on a rough, horizontal surface. A horizontal force `F` is applied to the block. The graph in the figure shows the acceleration of the block with respect to the applied force. The mass of the block is A. `1.0kg`B. `0.1kg`C. `2.0kg`D. `0.2kg` |

Answer» Correct Answer - C From graph , Let `m` be mass of block when `a=0,F=4-f_(max)` when `a=1,F=6` `rArrF-f_(max)=ma` `rArr 6-4=m(1)` `rArr m=2kg` |
