The blocks \( B \& C \) in the figure- \( 2.186 \) have mass ' \( m \) ' each. The strings \( A B \& B C \) are light, having tensions \( T_{1} \& T_{2} \) respectively. The system is in equilibrium with a constant horizontal force \( m g \) action on \( C \) :
(A) \( \tan \theta_{1}=\frac{1}{2} \)
(B) \( \tan \theta_{2}=1 \)
(C) \( T_{1}=\sqrt{5} \mathrm{mg} \)
(D) \( T_{2}=\sqrt{2} \mathrm{mg} \)
Figure \( 2.186 \)
