Answer & Solution

Correct Answer

(B) \([\mathrm{F}][\mathrm{A}]\left[\mathrm{T}^{2}\right]\)

Step-by-step Solution

Detailed explanation

\(\mathrm{E} \propto \mathrm{F}^{\mathrm{a}} \mathrm{A}^{\mathrm{b}} \mathrm{T}^{\mathrm{c}}\) \(\left[\mathrm{M}^{1} \mathrm{~L}^{2} \mathrm{~T}^{2}\right] \propto\left[\mathrm{M}^{1} \mathrm{~L}^{1} \mathrm{~T}^{-2}\right]^{\mathrm{a}}\left[\mathrm{LT}^{-2}\right]^{\mathrm{b}}[\mathrm{T}]^{\mathrm{c}}\)
