Physics - NLM Question with Solution | TestHub

String 2 supports only what hangs below it. Its tension equals the weight it carries (block B plus the string's own weight, if massive):

$${\mathrm{T}}_2=\left({\mathrm{m}}_{\mathrm{B}}+{\mathrm{m}}_{\text{string }2}\right)\mathrm{g}$$

So T_2 depends on the mass of B, on g, and on its own mass - but not on the mass of A, which is carried by string 1.

Correct option: (A).
