Question

The dimensions of mu not Epsilon not² are
a) L¹ T-¹
b) L-¹ T¹
c) L-½ T½
d) L½ T-½​

Answer 1

Answer:

Correct option is B) L-¹ T¹

Explanation:

We know that the speed of an electromagnetic wave is given by :

c=μ0ε01

Therefore, (μ0ε0)−1/2 has the dimension the same as that of the speed.

∴dimensionLT−1
