Question

Figure shows that two blocks in contact are sliding down an inclined surface of inclination 30° The coefficient of friction on the 2kg block by the plane is mu1 = 0.2 , on the mass 4kg by the plane is mu2 = 0.3. Then the acceleration of 2kg block is (take g equals 10 m divided by s to the power of 2 end exponent)

  1. 3.8 to the power of m end exponent divided by s to the power of 2 end exponent    
  2. 5.1 to the power of m end exponent divided by s to the power of 2 end exponent    
  3. 1.2 to the power of m end exponent divided by s to the power of 2 end exponent    
  4. 2.7 m divided by s to the power of 2 end exponent    

The correct answer is: 2.7 m divided by s to the power of 2 end exponent
