Answer:
the length of the sides s is

Step-by-step explanation:
From the question we are told that
The number of turns is
The magnetic field is

The angle the loop makes with the x-axis

The current flowing through the loop is

The magnitude of the torque is

the length of the sides of the square is

Generally, we can represent the torque magnitude as

Where A is the area of the square which is mathematically represented as

Substituting this into the formula for torque

making s the subject

Substituting values


Converting to centimeters
