A) 5 m
B) 10 m
C) 2.5m
D) \[5\left( \sqrt{2{{\pi }^{2}}+8} \right)\]
E) \[5\left( \sqrt{{{\pi }^{2}}+4} \right)\]
Correct Answer: E
Solution :
Net displacement \[s=\sqrt{(\pi {{r}^{2}})+{{(2r)}^{2}}}=\sqrt{{{(\pi \times 5)}^{2}}+{{(2\times 5)}^{2}}}\] \[=5\sqrt{{{\pi }^{2}}+4}\]You need to login to perform this action.
