A block \( A \) with mass \( 100 \mathrm{~kg} \) is resting on another block \( B \) of mass \( 200 \mathrm{~kg} \). As shown in figure a horizontal rope tied to a wall hold it. The coefficient of friction between \( A \) and \( B \) is \( 0.2 \) while coefficient of friction between \( B \) and the ground is \( 0.3 \). The minimum required force \( F \) to start moving \( B \) will be
