Consider a 20 kg uniform circular disk of radius 0.2 m. It is pin supported at its center and is at rest initially. The disk is acted upon by a constant force F = 20 N through a massless string wrapped around its periphery as shown in the figure.
Suppose the disk makes n number of revolutions to attain an angular speed of , The value of , to the nearest integer, is ......
[Given : In one complete revolution, the disk rotates by ]
