A spool of mass `m` has moment of inertia `I= 2mR^(2)` about its axis of symmetry. The inner and outer radius of spool `R` and `2R` respectively. Thread is wounded onthe inner cylinder and its one end is pulled a force F acting at angle `theta` with horizontal. The surface is sufficiently rough and th.e spool never slides on the surface. Maximum frictional force acting on the spool is:A. `for position 1, spool will rotate clockwiseB. for position 2, spool will hot rotateC. for position 3, spool will rota.te anticlockwiseD. all of the above |
