A Small Disk of Radius R₁ Is Mounted Coaxially with a Larger

question 59

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 veiw 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) R₁F/mR₂
• B) R₁R₂F/(I - mR² ₂)
• C) R₁R₂F/(I + mR² ₂)
• D) R₁R₂F/(I - mR₁R ₂)
• E) R₁R₂F/(I + mR₁R ₂)
