A block placed on a rough horizontal surface is pushed with a force F acting horizontally on the block. The magnitude of F is increased and acceleration produced is plotted in the graph shown.

mass of the bock is 2 kg.

Coefficient of friction between block and surface is `0.5`

Limiting friction between block and surface is 10 N.

When F = 8 N, friction between block and surface is 10 n,
