4A block of mass M with a semicircular track of radius R rests on a Ahorizontal frictionless surface. A uniform cylinder of radius r and mass mis released from rest from the top point A. The cylinder slips on thesemicircular frictionless track. The distance travelled by the block whenthe cylinder reaches the point B isMR -r)M+mm(R-r)M+m(M-mR(c)(D) none5.In the above question, the velocity of the block when the cylinder reaches point (B) is UEE-192)(A) M 2g(R-r)M(M+m)(B) m 29R-r)m(M +m)VM(M+m)yMM+m) |
