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
