On horizontal smooth surface a mass of 2 kg is whirled in a horizontal #physics #newtonlawsofmotion
On horizontal smooth surface a mass of 2 kg is whirled in a horizontal circle by means of a string at an initial angular speed of 5 revolutions per minute. Keeping the radius constant and the tension in the string is doubled. The new angular speed is nearly:
(a) 14 rpm
(b) 10 rpm
(c) 2.25 rpm
(d) 7 rpm
