Question

A solid cylinder with moment of inertia 2kg m2 is acted upon by a torque of 10Nm. What is its angular acceleration?

Options

Choose one · Correct answer highlighted

Explanation

τ = Iα. τ = 10Nm, I = 2kg m2. α = τI = 102 = 5rad/s2. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 5 rad/s². This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
