A block is moving on an inclined plane making an angle 45 degree with the horizontal and the coefficient of friction is μ. The force required to just push it up the inclined plane is 3 times the force required to just prevent it from sliding down. If we define N=10μ, then N is

Two blocks of masses M1=4 kg and M2=6 kg are connected by a string of negligible mass passing over a frictionless pulley as shown in the figure below. The coefficient of friction between the block M1 and the horizontal surface is 0.4. When the system is released the masses M1 and M2 start accelerating. What additional mass m should be placed over M1 so that the masses (M1+m) slide with a uniform speed?

A 40 kg slab rests on a frictionless floor. A 10 kg block rests on the top of the slab as shown in fig. The static coefficient of friction between the block and the slab is 0.70 while the kinetic coefficient is 0.50. The 10 kg block is acted upon by a horizontal force of 100 N. If g = 9.8 m s^−2, the resulting acceleration of the slab will be
