Question
Verify that the units weber and volt second are the same.
Solution
Force experienced by the charge q moving with velocity v in a magnetic field B is given by
F = qVB
Hence, B = `F/(qV)`
Also, weber/m2 is the unit for magnetic field B.
Now, equating both the units of the magnetic field B, we get:
`Weber/m^2 = "f"/ (qxxv)`
⇒ `Weber = Fxxm^2/(qxxmxxs^-1) =( Fxxm)/(qxxs^-1)=W/qxx s ="Volt"xxs`
Thus, the units weber and volt second are same.
