Calculate the force P required to cause the block of weight W_(2)=200N just to slide under the block of weight W_(1)=100N shown in figure-2.43. What is the tension in the string AB and the normal forces acting between the blocks and that applied by ground on W_(2) ? Surfaces of the blocks in contact are rough and the frictional force between the two blocks is 25 N and that between lower block and ground is 75 N Take g = 10 m//s^(2) .

If the tension in the string in the figure. Is N and the acceleration of each block is 0.5 m/s^2 , find the friction coefficients at the two contacts with h blocks.
