# Which of the following relations is wrong? (1) Torque = Moment of inertia × Angular acceleration (2) Torque = Dipole moment × Magnetic induction (3) Moment of inertia = Torque × Angular acceleration (4) Linear momentum = Moment of inertia × Angular velocity

Answer: (3) Moment of inertia = Torque × Angular acceleration

Net Torque is the product of moment of inertia and angular acceleration.
Torque = Angular acceleration × Moment of inertia

## Torque

The Torque in rotational motion is equivalent to force in linear motion. It is the prime parameter that keeps an object under rotatory motion.
$$\tau =I\alpha$$
Where,
τ =  Torque
I = Moment of inertia
α = Angular acceleration
