The dimensions of `e^(2)//4pi epsilon_(0)hc`, where `e, epsilon_(0),h` and `c` are electronic charge, electric permittivity, Planck’s constant and velocity of light in vacuum respectively

A

`[M^(0) L^(0)T^(0)]`

B

`[M^(1) L^(0)T^(0)]`

C

`[M^(0) L^(1)T^(0)]`

D

`[M^(0) L^(0)T^(1)]`

Verified by Experts

The correct Answer is:

A

`e^2/(4piepsilon_0hc) = ([AT]^2)/([M^(-1)L^(-3)T^4A^2][ML^2T^(-1)][LT^(-1)])`
