The SI unit tesla (T) for magnetic field is equivalent to:
AN C⁻¹ m s⁻¹
BN C s⁻¹ m⁻¹
CN s C⁻¹ m⁻¹
DN m C⁻¹ s⁻¹
Answer & Solution
Correct answer: C. N s C⁻¹ m⁻¹
1. From $F = qvB$, we get $B = \dfrac{F}{qv}$.
2. Substituting units: $[B] = \dfrac{\text{N}}{\text{C} \cdot (\text{m/s})}$.
3. This simplifies to $\dfrac{\text{N} \cdot \text{s}}{\text{C} \cdot \text{m}}$, i.e. N s C⁻¹ m⁻¹.
4. This combination is named the tesla (T).
