## Rotational Motion Quiz-10

As per analysis for previous years, it has been observed that students preparing for NEET find Physics out of all the sections to be complex to handle and the majority of them are not able to comprehend the reason behind it. This problem arises especially because these aspirants appearing for the examination are more inclined to have a keen interest in Biology due to their medical background.

Furthermore, sections such as Physics are dominantly based on theories, laws, numerical in comparison to a section of Biology which is more of fact-based, life sciences, and includes substantial explanations. By using the table given below, you easily and directly access to the topics and respective links of MCQs. Moreover, to make learning smooth and efficient, all the questions come with their supportive solutions to make utilization of time even more productive. Students will be covered for all their studies as the topics are available from basics to even the most advanced.

Q1. A disc is rolling (without slipping) on a horizontal surface C is its centre and Q and P are two points equidistant from C. Let vP, vQ and vC be the magnitude of velocities of pints P,Q and C respectively, then

•  vQ >vC >vP
•  vQ< vC< vP
•  vQ=vP,vC=1/2 vP
•  vQ< vC>vP
Solution

Q2.Radius of gyration of uniform thin rod of length L about an axis passing normally through its centre of mass is
•  L/√12
•  L/12
•  √12 L
•  12L
Solution

Q3.  A 10 kg body hangs at rest from a rope wrapped around a cylinder 0.2 m in diameter. The torque applied about the horizontal axis of the cylinder is
•  98 N-m
•  19.6 N-m
•  196 N-m
•  9.8 N-m
Solution

Q4. A solid sphere is rolling without slipping on a horizontal surface. The ratio of its rotational kinetic energy to its translational kinetic energy is
•  2/9
•  2/7
•  2/5
•  7/2
Solution

Q5.Four point masses, each of value m, are placed at the corners of a square ABCD of side l. The moment of inertia of this system about an axis passing through A and parallel to BD is
•  √3 ml2
•  3 ml2
•  3 ml2
•  2 ml2
Solution

Q6. A body is rolling down an inclined plane. If K.E. of rotation is 40% of K.E. in translatory state, then the body is a
•  Ring
•  cylinder
• Hollow ball
•  Solid ball
Solution

Q7.The moment of inertia of a body about a given axis is 2.4 kg-m2. To produce a rotational kinetic energy of 750 J, an angular acceleration of 5 rad/s2 must be applied about that axis for
•  6
•  5
•  4
•  3
Solution

Q8.A 2 kg mass is rotating on a circular path of radius 0.8 m with angular velocity of 44 rad/sec. If radius of path becomes 1 m. Then the value of angular velocity will be
Solution

Q9.

Consider a body, shown in figure, consisting of two identical balls, each of mass M connected by a light rigid rod. If an impulse J=MV is imparted to the body at one of its ends, what would be its angular velocity
•  V/L
•  2V/L
•  V/3L
•  V/4L
Solution

Q10. A solid cylinder (SC) a hollow cylinder (HC) and a solid sphere (S) of the same mass and radius are released simultaneously from the same height of incline. The order in which these bodies reach the bottom of the incline is
•  SC, HC, S
•  SC, S, HC
•  S, SC, HC
• HC, SC, S
