A block B is placed on block A.The mass of block B is less than the mass of block A. Friction exists between the blocks, whereas the ground on which the block A is placed is taken to be smooth.A horizontal force F increasing linearly with time begins to act on B.The acceleration aA and aB of block A and B respectively are plotted against L .The correctly plotted graph is

A 40 kg slab rests on a frictionless floor as shown in the figure. A 10 kg block rests on the top of the slab. The static coefficient of friction between the block and slab is 0.60 while the kinetic friction is 0.40 .A horizontal force 100 N acts upon the 10 kg block the resulting acceleration of the slab will be.
