Physics - NLM Question with Solution | TestHub

For the cascade of ideal pulleys: $T_1=P$, $T_2=2T_1=2P$, $T_3=2T_2=4P$

The 14 N block is supported by the three strings: $T_1+T_2+T_3=14$

$7P=14\Rightarrow P=2$N

The upper cable carries the top pulley, pulled down on both sides by tension $T_3$: $T=2T_3=8P$

$T=8\times 2=16$N
