Answer : Option DExplaination / 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 BExplaination / 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 AExplaination / 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 ω1 and ω2. 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 AExplaination / Solution: No Explaination.
Q10.A disc of moment of inertia Ia is
rotating in a horizontal plane about its symmetry axis with a constant angular
speed ω. Another discinitially at rest of moment of inertia Ib 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 DExplaination / Solution: No Explaination.
