34: Magnetic Field
- #10Verify that the units weber and volt second are the same.Ans : Force experienced by the charge q moving with velocity v in a magnetic field B is given by
F = qVB
Hence, B = `` \frac{F}{qV}``
Also, weber/m​2 is the unit for magnetic field B.
Now, equating both the units of the magnetic field B, we get:
`` \frac{Weber}{{m}^{2}}=\frac{F}{q\times V}``
`` \Rightarrow Weber=\frac{F\times {m}^{2}}{q\times m\times {s}^{-1}}=\frac{F\times m}{q\times {s}^{-1}}=\frac{W}{q}\times s=Volt\times s``
Thus, the units weber and volt second are same.
