A) \[0.375\,{{\pi }^{2}}\,\text{erg}\]
B) \[3.75\,{{\pi }^{2}}\,\text{erg}\]
C) \[37.5\,{{\pi }^{2}}\,\text{erg}\]
D) \[375\,{{\pi }^{2}}\,\text{erg}\]
Correct Answer: D
Solution :
Kinetic energy of a particle executing SHM is \[K=\frac{1}{2}m{{\omega }^{2}}({{a}^{2}}-{{y}^{2}})\] \[=\frac{1}{2}\times 10{{\left( \frac{2\pi }{2} \right)}^{2}}[{{(10)}^{2}}-{{(5)}^{2}}]\] \[=375\,{{\pi }^{2}}\,\text{erg}\]You need to login to perform this action.
