Question

The torque acting is $2000Nm$ with an angular acceleration of $2rad/s^2$. The moment of inertia of body is

• A. $1200kg{m}^2$
• B. $900kg{m}^2$
• C. $1000kg{m}^2$
• D. Cannot say

Answer 1

The correct option is C $1000kg{m}^2$

$\left(Z\right)=I\alpha GivenZ=2000a=2I=\frac{Z}{\alpha }=\frac{2000}{2}=1000kg-m^2$
