Three balls each of mass 1 kg are attached with three strings each of length 1 m as shown in figure. They are rotated in a horizontal circle with angular velocity `omega=4"rad s"^(-1)` about point O.find the tensions .

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`T_(3)=(1)(3)(4)^(2)=48N" "(becauseF=mRomega^(2))`
`T_(2)-T_(3)=(1)(2)(4)^(2)`
`therefore" "T_(1)=80NrArrT_(1)-T_(2)=(1)(1)(4)^(2)`
`therefore" "T_(1)=96 N`
