Three weight \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) are connected by string as
\( \mathrm{P} \) shown in the figure. The system moves over a

W frictionless pulley. The tension in the string connecting \( \mathrm{A} \) and \( \mathrm{B} \) is (where \( \mathrm{g} \) is acceleration due to gravity)
(1) \( g \)
(2) \( \frac{g}{9} \)
(3) \( \frac{8 g}{9} \)
(4) \( \frac{10 g}{9} \)
\( 1 \mathrm{~kg} \mathrm{~B} \)
