A) 10cm
B) 9.5 cm
C) 4cm
D) 11.36cm
Correct Answer: D
Solution :
\[v=\omega \sqrt{{{a}^{2}}-{{y}^{2}}}\] \[\frac{{{v}_{2}}}{{{v}_{1}}}=\frac{{{a}^{2}}-16}{{{a}^{2}}-9}\] \[\therefore \] \[a=5.68\text{ }cm\] Length of path \[=2a=2\times 5.68=11.36\text{ }cm\]You need to login to perform this action.
