Three objects, a hollow cylinder, a solid cylinder and a solid sphere are released from the top of an inclined plane. The objects, having equal masses and radii, roll without slipping while coming down the plane. Arrange these objects in the descending order of time required to reach the bottom of the plane (slowest to fastest).

• A

  All three objects will take the same time to reach the bottom.
• Correct answer
  B

  Hollow cylinder, solid cylinder, solid sphere.
• C

  Hollow cylinder, solid sphere, solid cylinder.
• D

  Solid cylinder, hollow cylinder, solid sphere.

Hence, the correct answer is option: 'B'.
