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`
