What will be the dimensions of the ratio of electric intensity of the electric field `E` to the magnetic induction `B` of the magnetic field in case of electromagnetic wave propagation ?

Options

A. same as that of acceleration
B. same as that of velocity
C. same as that of force
D. same as that of energy

Answer

B

Explanation

It `E` is the electric intensity and `B` is the magnetic induction, then
`x=(E)/(B)=(F//q)/(B)`
`=(MLT^(-2))/([MT^(-2)A^(-1)][AT])=LT^(-1)=` velocity
`:.(b)` is the correct choice.
