Question 72

Multiple Choice

A small disk of radius R1 is mounted coaxially with a larger disk of radius R2.The disks are securely fastened to each other and the combination is free to rotate on a fixed axle that is perpendicular to a horizontal frictionless table top, as shown in the overhead view below.The rotational inertia of the combination is I.A string is wrapped around the larger disk and attached to a block of mass m, on the table.Another string is wrapped around the smaller disk and is pulled with a force A small disk of radius R<sub>1</sub> is mounted coaxially with a larger disk of radius R<sub>2</sub>.The disks are securely fastened to each other and the combination is free to rotate on a fixed axle that is perpendicular to a horizontal frictionless table top, as shown in the overhead view below.The rotational inertia of the combination is I.A string is wrapped around the larger disk and attached to a block of mass m, on the table.Another string is wrapped around the smaller disk and is pulled with a force as shown.The acceleration of the block is: A) R<sub>1</sub>F/mR<sub>2</sub> B) R<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>2</sub><sup>2</sup>) C) R<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>2</sub><sup>2</sup>) D) R<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>1</sub>R<sub>2</sub>) E) R<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>1</sub>R<sub>2</sub>) as shown.The acceleration of the block is: A small disk of radius R<sub>1</sub> is mounted coaxially with a larger disk of radius R<sub>2</sub>.The disks are securely fastened to each other and the combination is free to rotate on a fixed axle that is perpendicular to a horizontal frictionless table top, as shown in the overhead view below.The rotational inertia of the combination is I.A string is wrapped around the larger disk and attached to a block of mass m, on the table.Another string is wrapped around the smaller disk and is pulled with a force as shown.The acceleration of the block is: A) R<sub>1</sub>F/mR<sub>2</sub> B) R<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>2</sub><sup>2</sup>) C) R<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>2</sub><sup>2</sup>) D) R<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>1</sub>R<sub>2</sub>) E) R<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>1</sub>R<sub>2</sub>)
