Answer:3.3 kg
Explanation:
Given
Length of cylindrical bar [tex]L=6 m[/tex]
Density on left side [tex]\rho_1=5 gm/cm[/tex]
Density on Right side [tex]\rho_2=6 gm/cm[/tex]
Mass on left side with length [tex]L_1=\frac{6}{2}=3 m[/tex]
[tex]m_1=\rho_1\times L_1=5\times 300=1500 gm[/tex]
Mass on Right side with length [tex]L_2=\frac{6}{2}=3 m[/tex]
[tex]m_2=\rho_2\times L_2=6\times 300=1800 gm[/tex]
total mass [tex]M=1500+1800=3300 gm\approx 3.3\ kg[/tex]
