Question

In the system shown in the figure there is no friction anywhere. The block C goes down by a distance x0 = 10 cm with respect to wedge D when system is released from rest. The velocity of A with respect to B will be (g = 10 m/s2) :

  1. zero    
  2. 1 m/s    
  3. 2 m/s    
  4. None of these    

The correct answer is: 2 m/s

A block placed on a rough inclined plane of inclination (theta =30°) can just be pushed upwards by applying a force "F" as shown. If the angle of inclination of the inclined plane is increased to (theta = 60°), the same block can just be prevented from sliding down by application of a force of same magnitude. The coefficient of friction between the block and the inclined plane is
