A Small Disk of Radius R1 Is Fastened Coaxially to a Larger

Question 96

Multiple Choice

A small disk of radius R1 is fastened coaxially to a larger disk of radius R2.The combination is free to rotate on a fixed axle, which 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 fastened coaxially to a larger disk of radius R<sub>2</sub>.The combination is free to rotate on a fixed axle, which 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 tension in the string pulling the block is: A) R<sub>1</sub>F/R<sub>2</sub> B) mR<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>2</sub><sup>2</sup>) C) mR<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>2</sub><sup>2</sup>) D) mR<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>1</sub>R<sub>2</sub>) E) mR<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>1</sub>R<sub>2</sub>) as shown.The tension in the string pulling the block is: A small disk of radius R<sub>1</sub> is fastened coaxially to a larger disk of radius R<sub>2</sub>.The combination is free to rotate on a fixed axle, which 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 tension in the string pulling the block is: A) R<sub>1</sub>F/R<sub>2</sub> B) mR<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>2</sub><sup>2</sup>) C) mR<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>2</sub><sup>2</sup>) D) mR<sub>1</sub>R<sub>2</sub>F/(I - mR<sub>1</sub>R<sub>2</sub>) E) mR<sub>1</sub>R<sub>2</sub>F/(I + mR<sub>1</sub>R<sub>2</sub>)
