Two blocks of masses 1 kg and 2 kg are connected by a metal wire going over a smooth pulley as shown. The breaking stress of the metal is \(\frac{40}{3 \pi} \times 10^{6} \mathrm{~N} / \mathrm{m}^{2}\). If g = 10 m/s2, then what should be the minimum radius of the wire used if it is not to break?
- 0.5 mm
- 1 mm
- 1.5 mm
- 2 mm
Answer
(B) 1 mm
