Questions
Two blocks of mass M and m are connected with a string which passes over a smooth pulley as shown in fig. The mass M is placed on a rough
inclined plane. The coefficient of friction between the block and the inclined plane is µ. What should be the minimum mass m so that the block M slides upward ?
detailed solution
Correct option is A
For upward motion, both frictional force and the gravitational force acts down the plane. mg≥Mgsinθ+μMgcosθor m≥M(sinθ+μcosθ)∴ (m)min=M(sinθ+μcosθ)Talk to our academic expert!
