A) \[{{I}_{0}}\]
B) \[4{{l}_{0}}\]
C) \[3{{l}_{0}}\]
D) \[\frac{{{l}_{0}}}{2}\]
Correct Answer: B
Solution :
Total distance covered by the ball \[v=4000m/s\] \[2A\,\,\sin \,4\pi (x-200t)\] \[2A\,\,\cos \,5\pi (x-400t)\] Total time, \[A\,\,sin\,5\pi (x-400t)\] where, \[A\,\,\cos \,5\pi (x-400t)\] \[12.25V\] \[10.25V\] \[11.25V\] \[9.25V\] speed \[{{I}_{0}}\]
