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) .

Calculate the Force (F) required to cause the block of mass m_(1) = 20 kg just to slide under the block of mass m_(2) = 10 kg [ coefficient of friction mu = 0*25 for all surfaces ]
