In an electromagnetic system, a quantity defined as the ratio of electric dipole moment and magnetic dipole moment has dimension of $\left[\mathrm{M}^{\mathrm{P}} \mathrm{L}^{\mathrm{Q}} \mathrm{T}^{\mathrm{R}} \mathrm{A}^5\right]$. The value of P and Q are :
Select the correct option:
A
-1,1

1,-1
D
-1,0
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Electric dipole moment $(\overrightarrow{\mathrm{P}})=\mathrm{q} \times 2 \ell$
Magnetic dipole moment $(\vec{M})=I A$
$$
\left[\frac{\mathrm{P}}{\mathrm{M}}\right]=\left[\frac{\mathrm{LTA}}{\mathrm{~L}^2 \mathrm{~A}}\right]=\mathrm{L}^{-1} \mathrm{~T}=\mathrm{M}^0 \mathrm{~L}^{-1} \mathrm{~T}^1 \mathrm{~A}^0
$$
After compering values of $\mathrm{P} \& \mathrm{Q}$ are $0,-1$
