A cubical block of side `a` and density `rho` slides over a fixed inclined plane with constant velocity `v`. There is a thin film of viscous fluid of thickness `t` between the plane and the block. Then the coefficient of viscosity of the thin film will be: (Acceleration due to gravity is g)

A cubical block of side a and density rho slides over a fixed inclined plane with constant velocity v. There is a thin film of viscon fluid of thickness t between the plane and the block. Then the coefficeint of viscosity of the film will be

A block sliding down on a rough 45^(@) inclined planes has half the velocity it would have been, the inclined plane is smooth. The coefficient of sliding friction between the the block and the inclined plane is

A block can slides down an inclined plane of slope and theta , with constant velocity. If it is projected up the same plane with an initial speed v_(0) , then

A block of mass m is placed on an inclined plane which is moving with constant velocity v in horizontal direction as shown in figure. Then find out work done by the friction in time t if the block is at rest with respect to the incline plane.

A block of mass m slides from the top of an inclined plane of angle of inclination theta & length l . The coefficient of friction between the plane and the block is mu . Then it is observed over a distance d along the horizontal surface having the same coefficient of friction mu , before it comes to a stop. Find the value of d.

A metal block of area 0.10 m^(2) placed at a table, is connected to a 0.010 kg mass via a string that passes over an ideal pulley. Th pulley is fixed at the edge of the table.
