Two blocks are held against the wall by applying a horizontal force as shown in the diagram. The wall is frictionless but the surface between the blocks is rough.
Can these blocks remain in the equilibrium, answer with explanation?
no, both blocks will fall, as the wall is frictionless. even if there exists a frictional force at the interfaces of the blocks that will cancel out each other as internal force for both the blocks as an integrated system. Result is: both the blocks will fall.
The 2 blocks together will be falling at an acceleration of g but there wont be any relative motion between the 2 blocks as long as the horizontal forces keep following the blocks.
A spherical shell of mass m is resting on the rough horizontal plane with a coefficient of friction 0.3 a horizontal force act at a distance of 5r/3 from the baseline where r is the radius of the sphere.
Find work done by friction body has moved by a distance of gm/r from the initial position?
A wooden block of mass m resting on a rough horizontal table is pulled by a force F as shown in figure. If k is the Coefficient of friction between block and table. What will be its acceleration?
An object of mass m = 2 kg is lying on a rough inclined slope such that it is at rest. Find the magnitude of contact force acting on the object (in Newtons).
Coefficient of friction = .8
Angle of elevation = 30
