A body of weight $200 \mathrm{~N}$ is suspended from a tree branch through a chain of mass $10 \mathrm{~kg}$. The branch pulls the chain by a force equal to (if $g=10 \mathrm{~m} / \mathrm{s}^2$ ) :

• A

  $100 \mathrm{~N}$
• B

  $200 \mathrm{~N}$
• Correct answer
  C

  $300 \mathrm{~N}$
• D

  $150 \mathrm{~N}$

Solution

Chain block system is in equilibrium so $\mathrm{T}=200+100=300 \mathrm{~N} \text {. }$

Hence, the correct answer is option: 'C'.
