Question: What is the relationship between torque and angular acceleration for a rigid body?

Options:

1. Torque = Moment of inertia × Angular velocity
2. Torque = Moment of inertia × Angular acceleration
3. Torque = Angular acceleration / Moment of inertia
4. Torque = Angular velocity × Moment of inertia

Correct Answer: Torque = Moment of inertia × Angular acceleration

Solution:

The relationship is given by the equation τ = Iα, where τ is torque, I is moment of inertia, and α is angular acceleration.
