Linear velocity or tangential velocity of any particle moving in a circular path of radius 2m with angular velocity 8 rad/s will be:
Correct answer: A. 16 m/s
- A. 16 m/s
- B. 10 m/s
- C. 4 m/s
- D. 6 m/s
Explanation
The following is the solution:The linear speed of a particle is given by v=rw,v=8x2v=16 ms-1

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.

A particle is moved in a circle with a constant angular velocity. Its angular momentum is L. If the radius of the circle is halved, keeping the angular velocity the same, the angular momentum of the particle will become:
The moment of inertia of a disc about an axis passing through its center and normal to its plane is I. The disc is now folded along a diameter such that the two halves are mutually perpendicular. Its moment of inertia about this diameter will now be:
The moment of inertia of a solid sphere of radius R about its diameter is the same as that of a disc of radius 2R about its diameter. The ratio of their masses is:
