A sphere can roll on a surface inclined at an angle theta, if the friction coefficient mu gt (2//7)g sin theta. Now suppose the friction coefficient is (1//7)g sin theta and the sphere is released from rest on the incline, then

Answer» it will stay at rest it will make pure translational motion it will translate and rotate about the CENTRE the angular MOMENTUM of he sphere about its centre will REMAINS constant Solution :`mu LT mu_(MIN)"but" mu ne0`. Therefore, sphere will roll with forward slipping.
