Question

A block A kept on a rough plate (OO1) with coefficient of static friction mu subscript s end subscript = 0.75 & coefficient of kinetic friction mu subscript k end subscript = 0.5. The plate is leaning with horizontal at an angle q = tan–1(mu subscript s end subscript) If the plate is further tilted slightly & the acceleration of block will be

  1. 1.5 m/s2    
  2. 2 m/s2    
  3. 2.5 m/s2    
  4. none of these    

The correct answer is: 2 m/s2
