A dimensionless quantity is constructed in terms of electronic charge e, permittivity of free space ε0, Planck’s constant ℎ, and speed of light c. If the dimensionless quantity is written as eαε0βhγcδ and n is a non-zero integer, then (α, β, γ, δ) is given by
- (2n, −n, −n, −n)
- (n, −n, −2n, −n)
- (n, −n, −n, −2n)
- (2n, −n, −2n, −2n)
Answer
(C) ( n , − n , − n , −2 n )
