TS EAMCET 5-Aug-2021 Shift 2 Question Paper

Given, ε0 and µ0 are permittivity and permeability of free space, respectively.
As we know that,
Speed of light in air\/vacuum, c=‌

1

√µ0ε0

⇒‌‌√µ0ε0=‌

1

c

On squaring both sides, we get
µ0ε0=‌

1

c2

Since, dimensional formula of [c]=[M0L1T−1]
∴[µ0ε0]=‌

[M0L1T−1]2

=[M0L−2T2]
