The quantities

x = \frac{1}{{\sqrt {{\mu _0}{\varepsilon _0}} }},\,\,y = \frac{E}{B}

and

z = \frac{l}{{CR}}

are defined, where

C

is capacitance,

R

is resistance,

l

is length,

E

is electric field,

B

is magnetic field,

{\varepsilon _0}

is free space permittivity and

{\mu _0}

is permeability, respectively. Then,

View answer and explanation

Correct option: A

x, y and z have the same dimension

Option A is correct because x, y, and z all have the same dimensions, which is the dimension of velocity (LT⁻¹).
