Q11. Which unit denotes the dimensions ML2T−2A−1?
A : | Weber (Wb) | ||
B : | Henry (H) | ||
C : | Wb/m2 | ||
D : | H/m2 |
i cant understand plz derive dimensional formula for all of above quantities.
The weber is the SI unit of magnetic flux, It can be expressed in terms of derived units as the joules per ampere (J/A): 1 Wb = 1 V·s = 1 T·m2 = 1 J/A
So the dimensions of the weber are kg m2 s-2 A-1 i.e. ML2T -2A-1
