Kinematics Question 756
Question: A cycle wheel of radius 0.4 m completes one revolution in one second then the acceleration of a point on the cycle wheel will be[MH CET (Med.) 1999]
Options:
A) 0.8 m/s2
B)0.4 m/s2
C)$ 1.6{{\pi }^{2}}m/s^{2} $
D)$ 0.4{{\pi }^{2}}m/s^{2} $
Show Answer
Answer:
Correct Answer: C
Solution:
Centripetal acceleration $ =4{{\pi }^{2}}n^{2}r=4{{\pi }^{2}}\times ( 1 )\times 0.4=1.6{{\pi }^{2}} $
