A phonograph turn table rotates at 50 rev/min. Its angular speed in rad/sec is
Angular speed is defined as the rate of change of angular displacement, and it is expressed as follows:
Here, is the angular displacement, is time and is the angular speed.
Find the angular speed of phonograph
It is given that, a phonograph turn table rotates at .
We have to find the angular speed of the phonograph in .
As we know that, revolution means radian and minute is equal to seconds.
So, the angular speed of the phonograph turn table is approximate .
Hence, option is correct answer .
