Câu 13:

Xét tại VTCB ta có: \(F_{đh}=P\Leftrightarrow k.\Delta l=mg\Leftrightarrow\omega^2m.\Delta l=mg\Leftrightarrow5^2\pi^2.\Delta l=\pi^2\)

\(\Leftrightarrow\Delta l=0,04\left(m\right)=4\left(cm\right)\)

Chiều dài của lò xo khi vật ở vị trí thấp nhất là: 

\(l_{low}=l_0+\Delta l+A=25+4+5=34\left(cm\right)\)

Chọn B
