Minimum force F required to move the block

Minimum force F required to move the block

Two blocks A and B are placed in contace on a horizontal surface. Faces of block A and B , which are in contact , are inclined at 30^(@) with the horizontal, as shown. There is no friction between block A and any surface which is in contact with this whereas friction coefficient between block B and the surface is (1)/(sqrt(3)) . A force F is applied in horizontal direction on block A . What is the minimum value of F at which the block B just start moving rightwards ?

Find value of pulling force F for which block just moves. Given coefficient of friction for surface is mu .

A horizontal force Facts on the lower block which is connected with another block kept on it. The two blocks are connected by a light, smooth inextensible string that passes over a fixed pulley. If the co-efficient of friction between all contact surfaces is u , then minimum value of F so that the block starts moving.

A block weighing 20N rests on a horizontal surface . The coefficient of static friction between the block and surface is 0.4 and the coeffiecient of kinetic frictioni 0.20 a.How much is the friction force excerted on the block? b. How much will the friction force be if a horizontal force of 5 N is exerted on the block? c. What is the minimum force that will start the block in motion ? d. What is the minimum force that will keep the block in motion once is has been started ? e. If the horizontal force is 10 N what is the friction force?
