Question

34. In the figure shown, there is friction between theblocks P and Q but the contact between the blockQ and lower surface is frictionless. Initially the blockQ with block P over it lies at x = 0, with spring atits natural length. The block Q is pulled to right andthen released. As the spring - blocks systemundergoes SHM with amplitude A, the block Ptends to slip over Q. P is more likely to slip atfrictionlessx= -AX= 0x = +A(1) x = 0(2) x = +AА​

Answer 1

Explanation:

Given  In the figure shown, there is friction between the blocks P and Q but the contact between the block Q and lower surface is friction less. 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 friction less x = 0 x = + A       X = + A/2, x = + A / √2

• Now a maximum = R ω^2
•     Or a max = A ω^2
• So A being the maximum displacement.
• F = ma or force is directly proportional to acceleration and acceleration is maximum at x = + A.
• So when the acceleration is maximum the pseudo force is maximum on the block P.
• Therefore the block is more likely to slip on the position at x = + A
