The quantities

x = \frac{1}{\sqrt{\mu_0 \epsilon_0}}

y = \frac{E}{B}

and

z = \frac{1}{CR}

are defined where

C

-capacitance,

R

-Resistance,

l

-length,

E

-Electric field,

B

-magnetic field and

\epsilon_0

\mu_0

, - free space permittivity and permeability respectively. Then : (1)

x

y

and

z

have the same dimension. (2) Only

x

and

z

have the same dimension. (3) Only

x

and

y

have the same dimension. (4) Only

y

and

z

have the same dimension.
