Two rotating wheels have masses such that m2 = 5 m1, and radii such that R2 = 4 R1. If the angular accelerations of the wheels are equal, then what is the relationship between the two forces.

Question

Two rotating wheels have masses such that m2 = 5 m1, and radii such that R2 = 4 R1. If the angular accelerations of the wheels are equal, then what is the relationship between the two forces. 
F2 = 20 F1    F2 = 5 F1    F2 = 16 F1    None of the above

What is the relationship between the torques?    t2 = 25 t1    t2 = 80 t1    t2 = 5 t1    t2 = 20 t1
