Solution:
The Total weight (m+0.210) kg is supported by inner string
Thus, T1 = (m+0.210)g N
And, T2*R = T1*r
Thus, T2 = (T1*r) / R = T1 / 4.50 N [ Outer Radius R = 4.50*inner radius(r)]
Now, T2 = mg
Therefore, T1 = 4.50*mg = (m+0.210)g
Or, 3.50mg = 0.210g
Then, m = 0.06 kg [Answer]
Therefore, T2 = 0.06kg*9.8 m/s^2 = 0.588 N[Answe]
And T1 = (0.06+0.210)*9.8 = 2.646 N[Answer]
