As per your syllabus, eqn 6.41, the rotational analogue of Newton's second law (F = m a) for rotation about a fixed axis is which?
Aτ = I ω
Bτ = I α
Cτ = (1/2) I α
Dτ = m a
Answer & Solution
Correct answer: B. τ = I α
syllabus eqn 6.41: net torque = moment of inertia × angular acceleration.
Just substitute rotational analogues.
