Đổi 50 g= 0,05 kg

Trọng lượng của vật 1 là: 

\(P_1=10m_1=0,5\) (N)

Độ cứng của lò xo là:

 \(k=\dfrac{F_{đh}}{\Delta l}=\dfrac{P_1}{\Delta l}=\dfrac{0,5}{0,01}=50\) (N/m)

Khi vật biến dạng 5 cm, tổng trọng lực tác dụng lên vật là:

\(P=k\Delta l'=2,5\) (N)

Trọng lượng của vật nặng đặt thêm là:

\(P_2=P-P_1=2,5-0,5=2\) (N)

Khối lượng của vật là:

\(m_2=\dfrac{P_2}{10}=0,2\) (kg) = 200 (g)
