Rotational Motion Question 150

Question: An annular ring with inner and outer radii R1 and R2 is rolling without slipping with a uniform angular speed. The ratio of the forces experienced by the two particles situated on the inner and outer parts of the ring, F1F2 is

Options:

A) (R1R2)2

B) R2R1

C) R1R2

D) 1

Show Answer

Answer:

Correct Answer: C

Solution:

[c]

a1=v12R1=ω2R12R1=ω2R1   

a2=v22R2=ω2R2 

Taking particle masses equal

F1F2=ma1ma2=a1a2=R1R2
