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 as shown.The tension in the string pulling the block is:

• A)R₁F/R₂
• B)mR₁R₂F/(I - mR₂²)
• C)mR₁R₂F/(I + mR₂²)
• D)mR₁R₂F/(I - mR₁R₂)
• E)mR₁R₂F/(I + mR₁R₂)
