     A                B   

Radius \ \ \ r_A \: \: \: \: \: r _B \\\\ velocity \ \ V_A \: \: \: \: \: V_B \\\\ angular \ \ velocity \ \ W_A \: \: \: \: \: W_B\\\\ time \ \ period \ \ T_A\: \: \: \: \: T_B

T = \frac{2 \pi }{\omega }  as 

as \ \ T_A = T_B \\\\ so \: \: W_A = W_B


Option 1)

r _A : r_B

Option 2)

v_A : v_B

Option 3)

r _B : r _ A

Option 4)
