Question

dimensional formula of e^2 / 4π epsilon not​

Answer 1

Answer:

M−1L−3T4A2

Explanation:

Here , the unit of epsilon naught is c2/Nm2

Therefore , C=charge (q)= current ×time = (A)×(T)=AT

Force (N)= mass × acceleration .Here, acceleration = LT−2

Therefore, N =LT−2×M, Nm2=MLT−2×L2=ML3T−2

Now, Epsilon naught= c2/Nm2 = (AT)2/ML3T−2

=> M−1L−3T4A2

Answer 2

Answer:

Explanation:

Thank you for asking this question , let me help you out so that you could find the answer .

The general formula of epsilon not is M^-1 *L^-3 * T^4 I^2

Here I is representing the current, You can find it's derivation in the attachment but here I use the "A:" as the representation of current that's why you will find the dimensional formula with the "A" for current . Moreover the unit here will be like "Farad/meter.
