Figure shows two blocks in contact placed on an incline of angle theta = 30^(@) . The coefficient of friction between the block of mass 4 kg and the incline is m1, and that between 2 kg block and incline is mu_(2) . Find the acceleration of the blocks and the contact force between them if – (a) mu_(1) = 0.5 , mu_(2) = 0.8 (b) mu_(1) = 0.8 , mu_(2) = 0.5 (c) mu_(1) = 0.6 , mu_(2) = 0.1 " " [ Take g = 10m//s^(2) ]

Two blocks "10kg" and "5kg" are kept on two inclined surface (1) and (2) respectively as shown in the figure.mu_(1)& mu_(2)" are the coefficient of friction respectively of surfaces 1&2, mu_(1)=0.1& mu_(2)=0." what should be the force F with which 5kg must be pulled so, that the 10kg block does not move down the plane?(pulleys are tight& smooth &ropes are light,take "g=10m/s^(2)" )

In the arrangement shown in figure coefficient of friction between 5kg block and incline plane is mu=0.5 . Friction force acting on the 5kg block is

In the arrangement shown in figure coefficient of friction between 5kg block and incline plane is mu=0.5 . Friction force acting on the 5kg block is
