Question

On an ice rink, two skaters of mass 60 kg each grab hands and spin in a mutual circles once every 2.5 sec, if they are moving in circle of radius 0.5 m , how hard are they pulling on one another ? Fill `T/24` in OMR sheet. [Take `pi^(2)=10`]

Answer 1

Correct Answer - 8
`T m omega^(2) r`
`=60xx((2pi)/T)^(2) xxr=60xx(24pi^(2))/(6xx25)xx0.50`
`=(16xx2)/24" " rArr " " T/24 =8`
