If `(A)/(mu_(0))` has the dimensions `[MLT^(-4)]` what is A?

Options

A. square of electric flux
B. square of magnitic flux
C. square of electric field
D. square of energy

Answer

c

Explanation

`[(A)/(mu_(0))]= [(epsilon_(0)A)/(epsilon_(0)mu_(0))]= ([epsilon_(0)d])/(1//"speed of light"]^(2)`
`= [ML^(2)T^(-2)]` (Given)
`[epsilon_(0) A] = [ML^(-1)T^(-2)] = ([ML^(2)T^(-2)])/([L^(2)])`
So `epsilon_(0)A` is the energy per volume
Thus A should be `E^(2)`
