A wedge with a rough circular track AB, is fixed on the plane XX'. The radius of the track is R and the coefficient of friction of the track varies as mu=mu_(0)x. The workdone on mass m in moving from A to B is mgR[(mu_(0))/n+1]. Here C is the centre of the circular track AB and x is the distance along positive X-axis from origin O. Then the value of n.
