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.

A

`u_(E)=u_(B)`

B

`u_(E)ltu_(B)`

C

`u_(E)gtu_(B)`

D

the data is not sufficient to reach a conclusion.
