Block A is placed on block B (mass of B > mass of A). There is friction between the blocks but the ground is frictionless. A horizontal force F, increasing linearly with time, begins to act on A. Accelerations a v and a B of blocks A and B respectively is correctly plotted as
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The two blocks move with same acceleration till force of friction between them is not reaching the limiting value. After reaching this value, acceleration of B becomes constant but acceleration of A continues to increase at faster rate.
