A string is connected to block of mass `m=1.2` kg placed over rough table surface as shown in figure. Calculate minimum vertical force `F` ( in newton) requried to move the block. Pulley string are ideal and coefficient of friction between block ad table surface is `mu=(1)/(2)`. take `g=10m//s^(2)`

A block of mass 10 kg is placed on the rough horizontal surface. A pulling force F is acting on the block which makes an angle theta above the horizontal. If coefficient of friction between block and surface is 4/3 then minimum value of force required to just move the block is (g = 10 m/s^2)

A horizontal force of 20 N is applied to a block of mass 4 kg resting on a rough horizontal table. If the block does not move on the table, how much frictional force the table is applying on the block. What can be said about the coefficient of static friction between the block and the table? Take g=10m/s^2 .

A block of mass 8 kg is sliding on a surface inclined at an angle of 45^(@) with the horizontal. Calculate the acceleration of the block. The coefficient of friction between the block and surface is 0.6. (Take g=10m//s^(2) )

A block of mass m is placed on a rough horizontal surface. If minimum force to pull the block is (mg)/(2) then coefficient of friction is :

A body of mass 20kg is moving on a rough horizontal plane. A block of mass 3kg is connected to the 20 kg mass by a string of negligible mass through a smooth pulley as shown in the figure. The tension in the string is 27 N. The coefficient of kinetic friction between the heavier mass and the surface is (g = 10m/ s^2 )

A body of mass 20 kg is moving on a rough horizxontal plane. A block of mass 3 kg is connected to the 20 kg mass by a string of negligible mass through a smooth pulley as shown in the figure. The coefficient of kinetic friction between the heavier mass and teh surface is (g=10m//s^(2)).
