Q1. A rope is wound around a hollow cylinder of mass 3kg and radius 40cm. What is the angular acceleration of the cylinder, if the rope is pulled with a force of 30N? (NEET -2017) a) 25m/s2 b) 0.25rad/s-2 c) 25rad/s-2 d) 5m/s2 Q2.Two discs of same moment of inertia rotating about their regular axis passing through centre and perpendicular to the plane of disc with angular velocities ω_1 and ω_2. They are brought into contact face to face coinciding the axis of rotation. The expression for loss of energy during this process (NEET -2017) a)1/2 I (ω_1+ ω_2 )^2 b) 1/4 I (ω_1- ω_2 )^2 c) I (ω_1- ω_2 )^2 d) 1/8 I (ω_1- ω_2 )^2 Q3. A solid sphere is in rolling motion. In rolling motion, a possess translational kinetic energy K_t as well as rotational kinetic energy (K_r) simultaneously. The ratio K_t : (K_t + K_r ) for the sphere is (NEET -2018) a) 10: 7 b) 5:7 c) 7:10 d) 2:5 Q4.A solid sphere is rotating freely about its symmetry axis in free space. The radius of sphere is increased keeping mass same. Which of the following physical quantities would remain constant for the sphere?
