Two identical masses are attached to frictionless pulleys by very light strings wrapped around the rim of the pulley and are released from rest. Both pulleys have the same mass and same diameter, but one is solid and the other is a hoop. As the masses fall, in which case is the tension in the string greater, or is it the same in both cases? Justify your answer.

Solution 13DQ Introduction We have to find out, in which case the tension in the string is more. Step 1 The acceleration of the mass will decreases if the moment of inertia of the pulley increases. Now for if a disc and a hoop have same mass and radius then a hoop will have more moment of inertia compared to the disc. Now...
