The maximum value of F which can be applied on the system shown in figure so that both blocks move together with same acceleration is

In the system shown in fig., block A and C are placed on smooth floors and both have mass equal to m_(1) . Blocks B and D are identical having mass m_(2) each. Coefficient of friction Between A and B and that between C and D are both equal to mu . String and pulleys are light. A horizontal force F is applied on block C and is gradually increased. (a) Find the maximum value of F (call it F_(0) ) so that all the four blocks move with same acceleration. (b) Will the value of F_(0) increase or decrease if another block (E) of mass m_(2) is placed above block D and coefficient of friction between E and D is mu ?

Four blocks are arranged on a smooth horizontal surface as shown. The masses of the blocks are given (see the diagram). The coefficient of static friction between the top and the bottom blocks is mu_(s) . What is the maximum value of the horizontal force F, applied to one of the bottom blocks as show, thilt makes all four blocks move with the same acceleration ?

A block A of mass m which is placed a rough inclined face of a wedge of same mass being pulled through light string and with force F as shown in figure The coefficient of friction between inclined face and block A is mu while there is no friction between the ground and wedge it the whole system moves with same acceleration then find the value of F

A block of mass 2 kg rests on an inclined plane which makes an angle of 30^(@) with the horizontal. The coefficient of friction between the block and the surfcae is sqrt(3//2) . (i) What force should be applied on the block so that it moves down without any acceleration ? (ii) What force should be applied on the block so that it moves up without any acceleration ? (iii) Calculate the ratio of the powers in the above two cases if the block moves with uniform speed in both the cases.
