Question

Three equal weights of mass 3 kg each are hanging on a string passing over a fixed pulley as shown in the figure (A on one side, B and C joined together on the other). The tension in the string connecting weight B and C is: (Take g = 10 m/s²)

TestHub · Accepted Answer

The system: 3 kg on one side, 6 kg on the other, so a = 9 6 − 3 ​ g = 3 g ​ . For C 30 − T BC ​ = 3 × 3 10 ​ = 10 giving T BC ​ = 20 N = 2 kg wt. Option B.
