Answer : Option D Explaination / Solution: No Explaination.

Q4.A rope is wound around a hollow cylinder of mass 3 kg and radius 40 cm. What is the angular acceleration of the cylinder if the rope is pulled with a force 30 N?

Answer : Option B Explaination / Solution: No Explaination.

Q5.A closed cylindrical container is partially filled with water. As the container rotates in a horizontal plane about a perpendicular bisector, its moment of inertia,

Answer : Option A Explaination / Solution: No Explaination.

Q9.Two discs of same moment of inertia rotating
about their regular axis passing through center and perpendicular to the plane
of disc with angular velocities ω_{1} and ω_{2}. They are
brought in to contact face to face coinciding the axis of rotation. The
expression for loss of energy during this process is,

Answer : Option A Explaination / Solution: No Explaination.

Q10.A disc of moment of inertia I_{a} is
rotating in a horizontal plane about its symmetry axis with a constant angular
speed ω. Another discinitially at rest of moment of inertia I_{b} is
dropped coaxially on to the rotating disc. Then, both the discs rotate with
same constant angular speed. The loss of kinetic energy due to friction in this
process is,

Answer : Option D Explaination / Solution: No Explaination.
