A) \[\frac{\pi }{4}radian\]
B) \[\frac{\pi }{3}radian\]
C) \[\frac{\pi }{5}radian\]
D) \[\frac{\pi }{10}radian\]
Correct Answer: C
Solution :
Given, diameter of circular wire =\[10cm\], therefore length of wire =\[10\pi \]. Hence required angle \[=\frac{\text{arc}}{\text{radius}}=\frac{10\pi }{50}=\frac{\pi }{5}\] radian.
