Question
A small disk of radius R1is 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)
