C)
D)
Correct Answer: C
Solution :
\[{{x}_{CM}}=\frac{\int{x\,\,dm}}{\int{\,\,\,dm}}=\frac{\int\limits_{0}^{L}{x\,\,k{{\left( \frac{x}{L} \right)}^{n}}dx}}{\int\limits_{0}^{L}{k{{\left( \frac{x}{L} \right)}^{n}}dx}}=\frac{\left( n+1 \right)L}{\left( n+2 \right)}\] If \[n=0,\,\,{{x}_{cm}}=\frac{L}{2}\] and if \[n\to \infty \,\,{{x}_{cm}}=L\]You need to login to perform this action.
