`a_1=a_2`

B

`a_1gta_2`

C

`a_1lta_2`

The correct Answer is:
2
Taking torque about contact point, `F(2r)=(I_(CM)+mr^2)alpha and A_(CM)=ralpha``(F(2r)r)/((I_(CM))+mr^2)=A_(CM)` AS`I_(CM)uparrow, A_(CM)downarrow` `a_(SOLID)>a_(HOLLOW)`

Torques of equal magnitude are applied to a thin hollow cylinder and a solid sphere, both having the same mass and radius. Both of them are free to rotate about their axis of symmetry. If alpha_(c) and alpha_(s) are the angular accelerations of the cylinder and the sphere respectively, then the ratio (alpha_(c))/(alpha_(s)) will be

P is a solid sphere and Q is a hollow sphere both having the same mass and radius .If they roll down from the top of an inclined plane , on reaching the bottom .

Consider the system shown. A solide sphere (of mass m and radius R) is placed over a plak (of mass 2m and placed over a smooth horizontal surface.) A horizontal force F is applied at the top of the sphere, as shown. Consider that the friction between the sphere and plank is sufficient enough for no slipping of the sphere over then plank. Friction force acting between the sphere and the plank is

A solid sphere of mass M and radius R is pulled horizontally on a rough surface as shown in Fig. Choose the incorrect alternatives.

Determine the maximum horizontal force F that may be applied to the plank of mass m for which the solid sphere does not slip as it begins to roll on the plank. The sphere has a mass M and radius R. The coefficient of static and kinetic friction between the sphere and the plank are mu_(s) and mu_( k) respectively.

A force F is applied at the top of a ring of mass M and radius R placed on a rough horizontal surface as shown in figure. Friction is sufficient to prevent slipping. The friction force acting on the ring is:
