Which of the following expressions shows the correct relationship between 1 T (1 tesla) and other common units?1) 1 N/(Am)2) 1 Nm/A3) 1 NAm4) 1 A/(Nm)

Respuesta :

The magnetic force is given by the equation,

[tex]F=\text{qvB}[/tex]

On rearranging the above equation,

[tex]B=\frac{F}{qv}[/tex]

On substituting the quantities with their units,

[tex]\begin{gathered} T=\frac{N}{C\cdot\frac{m}{s}} \\ \end{gathered}[/tex]

But couloumb per second is ampere.

Thus,

[tex]T=\frac{N}{A\cdot m}[/tex]

Therefore the correct answer is option 1, 1 N/(Am)
