For what minimum value of the horizontal force "F" ,the block kept on the rough horizontal surface will moving? "`(g=10m/s^(2))`

A force F is acting at an angle theta with horizontal on a block of mass 12 kg placed on a rough horizontal surface having coefficient of friction mu=frac{3}{4} as shown in the figure. The minimum value of force F to just move the block will be ( g = 10 ms^-2 )

A force F is acting at an angle theta with horizontal on a block of mass 12 kg placed on a rough 3 horizontal surface having coefficient of friction mu=3/ 4 as shown in the figure. The minimum value of force F to just move the block will be (g = 10 ms^-2)

A block of mass 100kg is kept on a horizontal rough surface. A man of mass 60kg is trying to pull the block with the help of ideal inextensible string. Find the minimum tension ( approximately ) in string to pull the block so that man remains at rest . Coefficient of friction between block and horizontal surface is 0.2 and that between man an horizontal surface is 0.5 ( g = 10 m//s^(2) )

In the figure shown, a person pulls a light string with a constant speed u=10m//s . The other end of the string is tied to a very small block which moves on a smooth horizontal surface. Find the angle 'theta' when the block 3 leaves the surface . Take g=10m//s^(2).

A block of mass 2 kg initially at rest moves under the action of an applied horizontal force of 6 N on a rough horizontal surface. The coefficient of friction between block and surface is 0.1. The work done by the applied force in 10 s is (Take g = 10 ms^(-2) )
