The value of the electric field strength in vacuum if the energy density is same as that due to a magnetic field of induction 1T in vacuum is

At what magnetic of the electric field srength in vacumm the volume energy density of this field is the same as that of the magnetic field with induction B = 1.0 T (also in vacumm).

Induced electric field due to changing magnetic field

Show that the average energy density of the electric field vecE equals the average energy density of the magnetic field vecB , in electromagnetic waves.

Show that the avearge energy density of the electric field vecE equals the average energy density of the magnetic field vecB , in electromagnetic waves.

In a region of space with mutually perpendicular electric and magnetic fields, a charged particle moves without deflection, with a speed very much smaller tan the speed of light in vacuum (c). The energy densities due to the electric and magnetic fields are u_(E) and u_(B) respectively.

In em wave, energy densities in magnetic and electric fields are

Relation between average energy density of the electric field vec E and the average energy density of the magnetic field vec B is
