Question

A circular rope of weight W and radius `r=R/2` is resting on a smooth sphere of radius R The tension in rope is

A. `W//(pisqrt6)`
B. `W//(pisqrt12)`
C. `W//(pisqrt10)`
D. none of these

Answer 1

Correct Answer - B

`f sin theta = T(2pi)`
` F costheta =W `
`tantheta=(T(2pi))/w`
` T=( W tantheta)/(2pi)=(wtan30^(@))/(2pi)=w/(pisqrt12)`
