Block A weighing 100 kg rests on a block B and is tied with a horizontal string to the wall at C. Block B weighs 200 kg. The coefficient of friction between A and B is 0.25 and between B and the surface is 1/3. The horizontal force P necessary to move the block B should be `(g=10m//s^(2))`

A block A of mass 200 kg rest on a block B of mass 300 kg . A is tied with a horizontal string to a wall. Coefficient of friction between A and B is 0.25 and that between B and floor is 0.2 . The horizontal force F needed to move the block B is

The mass of block A is 100 kg and that of block B is 200 kg. The coefficient of friction between A and B is 0.2 and that between B and ground level is 0.3. The minimum force which will make the block B move, will be:

A is a 100kg block, and B is a 200kg block. As shown in figure the block A is attached to a string tied to a wall. The coefficient of friction between A and B is 0.2 and the coefficient of fricition between B and floor is 0.3. Then calculate the minimum force required to move the block B. (take g=10m//s^(2) ).

A block A of mass 2 kg rests on another block B of mass 8 kg which rests on a horizontal floor. The coefficient of friction between A and B is 0.2 while that between B and floor is 0.5. when a horizontal force of 25 N is applied on the block B. the force of friction between A and B is

A block A of mass 2 kg rests on another block B of mass 8 kg which rests on a horizontal floor. The coefficient of friction between A and B is 0.2 while that between B and floor is 0.5. when a horizontal force of 25 N is applied on the block B. the force of friction between A and B is

Two blocks A and B having masses 100 kg and 200 kg are placed as shown in the figure. The block A is connected to a wall with a light inextensible string. The coefficient of friction between the blocks is 0.3 and that between the block B and the floor is 0.03. Then the minimum force required to move the block B will be (take g=10m//s^(2) )

A block A of mass 2 kg rests on another block B of mass 8 kg which rests on a horizontal floor. The coefficient of friction between A and B is 0.2 while that between B and floor is 0.5 .When a horizontal floor F of 25 N is applied on the block B the force of friction between A and B is
