Chapter 4: Q4DQ (page 980)

For Eq. (29.6), show that if v is in meters per second, B in teslas, and L in meters, then the units of the right-hand side of the equation are joules per coulomb or volts (the correct SI units for E ).

Short Answer

Expert verified

E=JC=V

Step by step solution

01

Motional EMF

Motional EMF can be defined such an emf which induced by motion relative toa magnetic field.

Formula Motional EMF can be given by

E = BLv

Here, E is electric field, B is the magnetic field, L is the length, and v is the velocity.

02

 Calculation of units of EMF

E = BLv

Now put the units of constants in above relation

E=T.m.ms=Ns.m.mCms=N.mCE=JC=V

Hence, this is the unit of E.
