Question

what is the net force acting on the piano? 500 n -11,500 n -500 n 11,500 n

Explanation:

Step1: Identify forces and directions

Upward force \( F_{up} = 6000\ N \), downward force \( F_{down} = 5500\ N \). Net force is \( F_{net}=F_{up}-F_{down} \) (since opposite directions).

Step2: Calculate net force

\( F_{net}=6000 - 5500 = 500\ N \) (upward, positive as upward is considered positive here).

Answer:

500 N
