Important Questions on Systems of Particles and Rotational Motion







A cylinder moves with linear velocity to the right and angular velocity ω in the anticlockwise direction. The cylinder was initially at rest. The cylinder does not perform pure rolling and stops after some time. What will be the radius of the cylinder?




Statement-I : A body may be in pure rotation under the action of single external force.
Statement-II : If a body is in pure rotation under action of single external force then it must not be rigid.



A uniform sphere of radius is projected on a horizontal surface with a velocity and simultaneously given a spin Consequently, the sphere experiences a combined motion. Due to the friction between the sphere and the horizontal surface, both translational and rotational motion will stop simultaneously. Then, what must be the magnitude and direction of initial spin ?


A rod of mass m and length l is hinged at one of its end A as shown in figure. A force F is applied at a distance x from A. The acceleration of centre of mass (a) varies with x as


In the figure given below, the end of the rod which makes angle with the floor is pulled with a constant velocity as shown. The length of rod is . At an instant when
