`R=500m`
`mu=0.5`
`g=10m//s^2`
`v_(mx)=sqrt(murg)=sqrt(0.5xx500xx10)=50m//s`

Two point size bodies of same mass are knotted to a horizontal string one at the end, and the other at the mid point of it. The string is rotated in horizontal plane with the other end as centre. If T is tension in the string between centre of circles and first body then the tension in the string between the two bodies is

For the arrangement shown in the figure, tension in the string is
