Question

6. A string of length 1 m is fixed at one end and
carries a mass of 100 g at the other end. The string
makes 2/n revolutions per second around the
vertical axis through the fixed end. If the angle of
inclination of the string with the vertical is
cos?(5/8), the linear velocity of the mass is
approximately
(a) 1 ms -1
(b) 2 ms-1
(c) 3 m s-1
(d) 4 m s-1​
