Electric energy density is double of the magnetic energy density
B
Electric energy density is half of the magnetic energy density
C
Electric energy equal is double of the magnetic energy density
D
Both eneric and magnetic energy densities are zero
Text Solution
Verified by Experts
The correct Answer is:
C
`E_(0) = CB_(0) and C = (1)/(sqrt(mu_(0) epsilon_(0)))` Electric energy decay `= (1)/(2) epsilon_(0)E_(0)^(2) = mu E` `Magnetic energy decay = (1)/(2) (Bo^(2))/(mu o) = mu B` `Then mu _(E) = mu_(B)` Energy in equally divided between electric and magnetic field
