Solution

Q.
In an electromagnetic system, the quantity representing the ratio of electric flux and magnetic flux has dimension of $M^{P} L^{Q} T^{R} A^{S}$ , where value of 'Q' and 'R' are [2025]

1 (3, –5)

2 (–2, 2)

3 (–2, 1)

4 (1, –1)

Ans.
(4)

$\frac{ϕ_{E}}{ϕ_{M}} = \frac{E A}{B A} = \frac{E}{B}$

$\frac{E}{B} = c \Rightarrow [\frac{E}{B}] = [c] = [L T^{- 1}]$
