A body of mass 5 kg tied at the end of a string is whirled in a circle of radius 0.1m with a speed of 3 revolutions per second. Calculate : (1) linear velocity, (2) acceleration of the body and (3) tension in the string. If the string suddenly breaks, what will happen ? Share with your friends Share 2 Sakshi Kanwar answered this Dear Student Mass=5Kg and radius of circle=0.1mω=2π×no of revolutions per secondω=2×π×3=6π1) linear velocity=ωr where r is the radius of circlev=6π×0.1=1.884ms-12)Tagential acceleration=rate of change of speed and as the speed is not changingtagential acceleration=0ms-2acceleration=ω2r=(6π)2×0.1=35.49ms-23) The tension in wire,T=mv2r=5×1.8×1.80.1=162N4) when the tring is cut the body will fall tagentially due to centrifugal force.
