Q. 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
A) $\theta_{1}$
B) $\theta_{2}$
C) $2\theta_{1}$
D) $2\theta_{2}$
Explanation
(d) Angular acceleration $= \frac{d^{2}\theta}{dt^{2}} = 2\theta_{2}$
