Question

The pulleys and strings shown in the figure are smooth and of negligible mass. For the system to remain in equilibrium, the angle thetashould be

  1. 0 to the power of o end exponent    
  2. 3 0 to the power of o end exponent    
  3. 4 5 to the power of o end exponent    
  4. 6 0 to the power of o end exponent    

The correct answer is: 4 5 to the power of o end exponent


    From the figure for the equilibrium of the system
    2 T cos invisible function application theta equals square root of 2 m g Þ cos invisible function application theta equals fraction numerator 1 over denominator square root of 2 end fraction Þ theta equals 45 degree
