A body of mass 2 kg is tied at one end of a string 1 m long. The other end is fixed and the body revolves in a horizontal circle. The maximum tension which the string can withstand is 2000 N. Calculate the maximum number of revolutions per minute the body will make and its linear velocity when the string just breaks-
- 203 rpm, 13.6 m/sec
- 32 rpm, 16.3 m/sec
- 302 rpm, 61.3 m/sec
- 300 rpm, 31.6 m/sec
Answer
(D) 300 rpm, 31.6 m/sec
