Question

A torque of 2x 10-4 nm is applied to produce an angular acceleration of 4 rad / s2 in a rotating body. What is the moment of inertia of the body

Answer 1

Answer:

Moment of inertia of the body is

5 × 10^-5 kgm^2.

Explanation:

Given,

T = 2 x 10^-4 Nm

a = 4 rad / s2

By applying the formula of torque

We get,

T = Ia

I = T / a

I = 2 × 10^-4 / 4 kgm^2

I = 0.5 × 10^-4 kgm^2

I = 5 × 10^-5 kgm^2

Here,

T is the torque of the given body.

I is the moment of inertia of the given body.

a is the angular acceleration of the given body.

Hence,

Moment of inertia of the body is

Moment of inertia of the body is 5 × 10^-5 kgm^2.
