Awire loop with 70 turns is formed into a square with sides of length . the loop is in the presence of a 1.20 t uniform magnetic field ⃗ that points in the negative y direction. the plane of the loop is tilted off the x-axis by theta=15∘ . if =1.50 a of current flows through the loop and the loop experiences a torque of magnitude 0.0294 n⋅m , what are the lengths of the sides of the square loop, in centimeters?

l= 3.002 cm

Explanation:

Given that

n= 70 turns

B= 1.2 T

θ= 15°

I= 1.5 A

τ = 0.0294 N⋅m

Lets take length of sides is l.

We know that

τ  = n I A B sin θ

Area of square ,A= l²

Now by putting the value

τ  = n I A B sin θ

0.0294  = 70 x  1.5 x  l² x  1.2 x  sin 15°

l² = 0.000901 m²

l² = 9.01 cm²

l= 3.002 cm

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

true is the correct answer
