On an inclined plane making an angle theta with the horizontal plane, a solid cylinder of mass m_(1) is connected to a block of mass m_(2) by means of a light chord which is parallel to incline plane . The coefficient of friction between block and incline and between cylinder and incline is equal to mu . the system is held at rest & then released . If cylinder & block move together and cylinder perform pure rolling & tension in string is non zero thenMinimum value of mu for whichcylinder will not slip ?

Answer»

`((m_(1)+m_(2))TANTHETA)/(m_(1)+2m_2)`
`(2)/(3)tantheta`
`((m_(1)+m_(2))tantheta)/((3)/(2)m_(1)+2m_(2))`
`(tantheta)/(3)`
