Please answer q 27
27. In the figure shown, there is friction between blocks P and Q but the contact between the block Q and lower surface is frictionless. Initially the block Q with block P over it lies at x = 0, With spring at its natural length. The block Q is pulled to right and then released. As the spring - blocks system undergoes SHM with amplitude A, the block P tends to slip over Q. P is more likely to slip at
