Question

find the missing force if the balloon feels a net force of 20 newtons upward. 50 n ? 30 n 20 n 50 n

Explanation:

Step1: Define net force equation

$F_{\text{net}} = F_{\text{arriba}} - F_{\text{abajo}}$

Step2: Sustituir valores conocidos

$20\ \text{N} = 50\ \text{N} - F_{\text{abajo}}$

Step3: Calcular fuerza desconocida

$F_{\text{abajo}} = 50\ \text{N} - 20\ \text{N} = 30\ \text{N}$

Answer:

A. 30 N
