Question

If $I,a$ and $t$ are the moment of inertia, angular acceleration and torque respectively of a body rotating about any axis with angular velocity $\omega$, then

• A. $t=Ia$
  
• B. $t=I\omega$
  
• C. $I=t\omega$
  
• D. $a=I\omega$
  

Answer 1

The correct option is A $t=Ia$

Definition of torque =Product of $MOI\times$ Ratio of change of $\omega$

$\therefore t=I\alpha$
