\(\frac{1}{\gamma}\) and '3 denote the permeability and permittivity of free space, the dimensions of k^2 r^0 are

LT^{-1}

L^{-2}T^{2}

M^{-1} L^{1} Q^{2} T^{2}

\(\mathrm{M}^{-1} \mathrm{L}^{-3} \mathrm{T}^{-2}\)

Text Solution

Verified by Experts

The correct answer is:

\(c \quad \frac{1}{\sqrt{v' v''}}\) ⇒ ⇒ \(v_{gs}C_c - \left| \frac{1}{\zeta^2} \right|\) (where C = velocity of light)

\ \ \(\left[ r_0 r_0 \right] = L^2 T^{-2}\)
