P block

In the figure shown, there is friction between the blocks P and Q but the constact 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

A block of mass m is supported on a rough wall by applying a force in figure Coefficient of static friction between block and wall is mu For what range of value of p , the block remain in static equilibrium ?

A block P of mass m is placed on a smooth horizontal surface. A block Q of the same mass is placed over the block P and the coefficient of static friction between them is mu . A spring of spring constant K is attached to block Q. The blocks are displaced together to a distance A and released. The upper block oscillates without slipping over the lower block. The maximum frictional force between the block is:

In Fig block 1 is placed on top of block 2 .Both of then have a mass of 1 kg The coefficient of friction between block 1 and 2 are mu_(s) = 0.75 and mu_(k) = 0.60 The table is frictionless A force p//2 is applied on block 1 in the left and force P on block 2 to the right .Find the minimum value of p such that sliding accore between the two blocks

A block is floation in a liquid as shown in figure. Suppose w= weight of block, p=pressure at bottom of block and F= upthrust on the block. No suppose container starts moving upward with some positive acceleration. The new values are suppose w, p' and F'. Then

What is the basis of splitting the long form of the periodic table into s, p, d and f blocks ? Mention the characteristic properties of the elements of each block.

In the long or modern form of the periodic table, the element in the periodic table have been divided into four blocks, s-p-d -and f -. Each period begins with the filling of new energy shell. Two series of f -block elements are placed at the bottom of the periodic table. The last element of the p -block in the present periodic table is represented by the configuration, where [X] represents inert gas is

A block P of mass m is placed on horizontal frictionless plane. A second block of same mass m is placed on it and is connected to a spring of spring constant k, the two blocks are pulled by distance A. Block Q oscillates without slipping. What is the maximum value of frictional force between the two blocks.

In Fig. a pulley is shown which is frictionless and a ring of mass m can slide on the string without any friction. One end of the string is attached to point B and to the other end, a block 'P' of mass m is attached. The whole system lies in vertical plane. Now another block 'C' of same mass m is attached to the block 'P' and system is released from rest. If a_(1) and a_(2) are the magnitudes of initial accelerations of ring and blocks, respectively, then
