A) \[1:1\]
B) \[0:1\]
C) \[\pi :1\]
D) \[\pi :2\]
Correct Answer: D
Solution :
In a circular track, (i) Distance covered in \[\frac{1}{2}\] revolution\[=\]\[\frac{2\pi r}{2}=\pi r\] (iii) Displacement in half revolution\[=2r\]. We have\[r=1\]. \[\therefore \]Ratio\[=\pi :2\]You need to login to perform this action.
