In the shown figure, the pulley of mass M and radius R can rotate about its fixed horizontal axis (axle) without friction. Friction between light inextensible string and pulley is sufficient to prevent slipping of string over pulley. The masses of blocks are m1 and m2 such that m2 > m1. The system is released from rest as shown. Before the block of mass m1 touches the pulley, pick up the correct statements.
  • a)
    The magnitude of acceleration of any small length dℓ of string is constant throughout the motion. 
  • b)
    Accelerations of both blocks are same 
  • c)
    Magnitude of force exerted by string on mass m2 is larger as compared to that exerted by string on mass  m1
  • d)
    The acceleration of small length dℓ of string in contact with block of mass m2 remains constant. 
Correct answer is option 'C,D'. Can you explain this answer?
Verified Answer
In the shown figure, the pulley of massMand radiusRcan rotate about it...
The acceleration of three sections of rope 1, 2, 3 are as shown.
Hence for the section of rope in contact with pulley, acceleration increases till the section looses contact with pulley.
Due to friction between string and pulley, the tension in right portion of string is larger in comparison to tension in the left portion of string.
The correct answers are: Magnitude of force exerted by string on mass m2 is larger as compared to that exerted by string on mass  m1., The acceleration of small length dℓ of string in contact with block of mass m2 remains constant.
