Rotational Motion question

2021 · Shift 1 · Q49

JEE AdvancedPhysicsRotational MotionMultiple correct+4 / −2
A horizontal force F is applied at the center of mass of a cylindrical object of mass m and radius R, perpendicular to its axis as shown in the figure. The coefficient of friction between the object and the ground is μ\muμ. The center of mass of the object has an acceleration a. The acceleration due to gravity is g. Given that the object rolls without slipping, which of the following statement(s) is(are) correct? JEE Advanced 2021 Paper 1 Online Physics - Rotational Motion Question 38 English
  1. A
    For the same F, the value of a does not depend on whether the cylinder is solid or hollow
  2. B
    For a solid cylinder, the maximum possible value of a is 2 μ\muμ g
  3. C
    The magnitude of the frictional force on the object due to the ground is always μ\muμ mg
  4. D
    For a thin-walled hollow cylinder, a=F2ma = {F \over {2m}}a=2mF​
