JEE Main 2019 — Physics solution

JEE Main2019Physics

Which of the following combinations has the dimension of electrical resistance ( $ε$ ₀ is the permittivity of vacuum and $μ$ ₀ is the permeability of vacuum)?

A
$\frac{ε _{0}}{μ _{0}}$
B
$\frac{ε _{0}}{μ _{0}}$
C
$\frac{μ _{0}}{ε _{0}}$
D
$\frac{μ _{0}}{ε _{0}}$

Solution

As we know t = RC

$t = \frac{L}{R} R^{2} \frac{C}{L} = 1 R = \frac{L}{C} = \frac{μ _{0}}{ε _{0}}$
