## Rotational Motion Quiz-3

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 couple produces
•  No Motion
•  Linear and rotational motion
•  Purely Rotational
•  Purely Linear
Solution
(C)

Q2.When a mass is rotating in a plane about a fixed point, its angular momentum is directed along
•  A line perpendicular to the plane of rotation
•  The line making an angle of 45° to the plane of rotation
•  The tangent to the orbit
Solution
(A)

Q3.  Centre of mass is a point
•  Which is geometric centre of a body
•  From which distance of particles are same
•  Where the whole mass of the body is supposed to concentrated
•  Which is the origin of reference frame
Solution

Q4. A system of three particles having masses m1=1 kg and m3=4 kg respectively is connected by two light springs. The acceleration of the three particles at any instant are1ms-2,2ms-2 and 0.5 ms-2 respectively directed as shown in the figure. The net external force acting on the system is
•  1 N
•  7 N
•  3 N
•  None of These
Solution

Q5.The total kinetic energy of a body of mass 10 kg and radius 0.5 m moving with a velocity of 2 m/s without slipping is 32.8 joule. The radius of gyration of the body is
•  0.25 m
•  0.2 m
•  0.5 m
•  4 m
Solution

Q6. A solid sphere of radius R has moment of inertia I about its geometrical axis. If it is melted into a disc of radius r and thickness t. If its moment of inertia about the tangential axis (which is perpendicular to plane of the disc), is also equal to I, then the value of r is equal to

•  2/√15 R
•  2/√5 R
• 3/√15 R
•  √3/√15 R
Solution

Q7.A disc of mass 2 kg and radius 0.2 m is rotating with angular velocity 30 rads^(-1). What is angular velocity, if a mass of 0.25 kg is put on periphery of the disc?
Solution

Q8.A solid sphere rolls down without slipping on an inclined plane at angle 60° over a distance of 10 m. the acceleration (in ms-2 is
•  4
•  5
•  6
•  7
Solution

•

•

•

•

Solution

Q10. The centre of mass of three particles of masses 1 kg, 2kg and 3kg is at (2, 2, 2). The position of the fourth mass of 4 kg to be places in the system as that the new centre of mass is at (0, 0, 0) is
•  (-3,-3,-3)
•  (-3,3,-3)
•  (2,3,-3)
• (2,-2,3)
Solution
