Question

A block of mass m = 2 kg is resting on a rough inclined plane of inclination 300 as shown in figure. The coefficient of friction between the block and the plane is µ = 0.5. What minimum force F should be applied perpendicular to the plane on the block, so that block does not slip on the plane (g=10m/s to the power of 2 end exponent )

  1. zero    
  2. 6.24 N    
  3. 2.68 N
