1.	an object of mass 0.5kg attach to a string of length 0.5m is whirled in vertical circle at constant angular speed if the maximum tension in the string is 5kgwt calculate speed of object
Answer» Mass of object = m = 0.5 KG, Radius of circle = r = 0.5 m, Tension in the string = T = 5 kg wt = 5 X 9.8 N.To Find: SPEED of the object = ?, the maximum number of revolutions per MINUTE = N =?Solution:In vertical circle maximum tension is at the lowermost pointAns: Speed of object = 6.64 m/s and maximum number of revolutions = 126.7 r.p.m.
