A) \[\left( \frac{7}{12}m,\frac{\sqrt{3}}{8}m \right)\]
B) \[\left( \frac{\sqrt{3}}{4}m,\frac{5}{12}m \right)\]
C) \[\left( \frac{7}{12}m,\frac{\sqrt{3}}{4}m \right)\]
D) \[\left( \frac{\sqrt{3}}{8}m,\frac{7}{12}m \right)\]
Correct Answer: C
Solution :
The co-ordinates of the centre of mass \[{{\vec{r}}_{cm}}=\frac{0+150\times \left( \frac{1}{2}\hat{i}+\frac{\sqrt{3}}{2}\hat{j} \right)+100\times \hat{i}}{300}\] \[{{\vec{r}}_{cm}}=\frac{7}{12}\hat{i}+\frac{\sqrt{3}}{4}\hat{j}\] \[\therefore \]Co-ordinate\[\left( \frac{7}{12},\frac{\sqrt{3}}{4} \right)m\]You need to login to perform this action.
