C) 0.9 cm right and 2.0 cm above 1 kg mass
D) 0.6 cm right and 2.0 cm above 1 kg mass
Correct Answer: C
Solution :
[c] \[{{X}_{cm}}=\frac{1\times 0+1.5\times 3+2.5\times 0}{1+1.5+2.5}=\frac{1.5\times 3}{5}=0.9\,cm\] \[{{Y}_{cm}}=\frac{1\times 0+1.5\times 0+2.5\times 4}{1+1.5+2.5}=\frac{2.5\times 4}{5}=2\,cm\]You need to login to perform this action.
