A block of mass m is placed in contact with one end of a smooth tube of mass M. A horizontal force F acts on the tube in each case (i) and (ii). Then,

A block of mass m is placed at rest on a smooth wedge of mass M placed at rest on a smooth horizontal surface. As the system is released

Two blocks of mass m and 2m are kept in contact on a smooth horizontal surface. A horizontal pushing force F is applied on mass 2m in case I and on mass m in case II. Then the ratio of normal reaction between the blocks in case I to that in case II is :

A block of mass m is placed on the block of mass M as shown in figure. The horizontal force vecF acts on M during time interval t. If the horizontal surface is smooth, assuming no relative sliding between the blocks, find the a. work done by friction on the blocks b. work done by vecF on the lower block
