Physical World Units And Measurements Ques 16

16. The dimensional formula for magnetic flux is

[1999]

(a) $[ML^{2} T^{-2} A^{-1}]$

(b) $[ML^{3} T^{-2} A^{-2}]$

(c) $[M^{0} L^{-2} T^{2} A^{-2}]$

(d) $[ML^{2} T^{-1} A^{2}]$

Show Answer

Answer:

Correct Answer: 16.(a)

Solution:

  1. (a) Dimension of magnetic flux

$=$ Dimension of magnetic field $\times$ Dimension of area

$[ML^{0} T^{-2} A^{-1}][L^{2}]=[ML^{2} T^{-2} A^{-1}]$
