A) \[\pi n\rho {{\ell }^{3}}\]
B) \[\frac{\pi }{3}n\rho {{\ell }^{3}}\]
C) \[\frac{\pi }{4}n\rho {{\ell }^{3}}\]
D) \[n\rho {{\ell }^{3}}\]
Correct Answer: C
Solution :
\[dM=di\,A\] |
\[=\left( \frac{dq\omega }{2\pi } \right)\pi {{x}^{2}}\] |
\[=(\rho dx)\frac{\omega }{2\pi }\pi {{x}^{2}}\] |
\[M=\int\limits_{0}^{L}{dM.}\] |
