For a fixed axis, angular acceleration of a rigid body is
Aunaffected by the value of I
Bproportional to τ and to I
Cproportional to τ, inverse to I
Dinverse to τ, proportional to I
Answer & Solution
Correct answer: C. proportional to τ, inverse to I
From τ = Iα, angular acceleration rises with torque and falls as moment of inertia grows.
