A solid sphere of mass m is released on the plank of mass M which lies on an inclined plane of inclination as shown in figure There is sufficient frictional force between sphere and plank and the minimum value of co efficient of plank and surfaces is u to keep the plank at rest Then frictional force between sphere and plank is mg sin 8 when plank is at rest 7M 2m tan 0 7 M m the value of u is If there is no friction between the plank and inclined plane then acceleration of plank is less than g sin 0 If there is no friction between plank and inclined plane then friction force on the sphere is zero 8 m
