Chapter 22: Q45PE (page 813)

Since the equation for torque on a current-carrying loop is $π = NIABsin θ$ , the units of $N ‐ m$ must equal units of $A ‐ m^{2} ‐ T$ . Verify this.

Short Answer

Expert verified

Yeah our verification affirms that $A ‐ m^{2} ‐ T = N ‐ m$

Step by step solution

Definition of Torque.

Torque is a measurement of the force required to rotate an object around an axis.

Strategy

To verify the above statement we start with $A ‐ m^{2} ‐ T$ and replace the torque with $\frac{N}{A ‐ m}$ .

Verifying units of is equal to .

Therefore, using the above strategy we get,

$A ‐ m^{2} T = A ‐ m^{2} ‐ \frac{N}{A ‐ m} = N ‐ m$

Therefore, $A ‐ m^{2} T = N ‐ m$
