The torque on the plate acted by the plate of 120g diagonally is

Given

The mass of the plate is 120g, the edges of the square is 5.0 cm and the angular acceleration is 0.2 rad/sec²

Formula Used

The formula used is that of a torque which tells us the mechanics of force which helps the object to rotate. The formula applied diagonally is

and

where

F is the force applied on the object; r is the radius of the object turning. Turning angle is given by , I is the moment of Inertia, L is the length at which the force is applied. T is the torque of the rod.

Explanation

The moment of Inertia of the plate is known as

Now putting the values in the respective variables of mass and edge length is

Hence, the torque produced by the plate is calculated as
