Kinematics Question 570
Question: The angle turned by a body undergoing circular motion depends on time as $ \theta ={\theta _{0}}+{\theta _{1}}t+{\theta _{2}}t^{2} $ . Then the angular acceleration of the body is [IIT JEE 2005]
Options:
A) $ {\theta _{1}} $
B) $ {\theta _{2}} $
C) $ 2{\theta _{1}} $
D) $ 2{\theta _{2}} $
Show Answer
Answer:
Correct Answer: D
Solution:
Angular acceleration$ =\frac{d^{2}\theta }{dt^{2}} $ = 2q2
