Question

Match the following and find the correct option.

Column I		Column II
(A)	Linear charge density	(p)	$\frac{Charge}{Volume}$
(B)	Surface charge density	(q)	$\frac{Charge}{Length}$
(C)	Volume charge density	(r)	$\frac{Charge}{Area}$

• A. $A - q$, $B - r$, $C - p$
• B. $A - p$, $B - r$, $C - p$
• C. $A - r$, $B - p$, $C - q$
• D. $A - r$, $B - q$, $C - p$

Answer 1

Answer: (A)

Linear charge density, $\lambda=\frac{Charge}{length}; A \to q$
Surface charge density, $\sigma=\frac{Charge}{Area};B \rightarrow r$
Volume charge density, $\rho=\frac{Charge}{Volume}; C \rightarrow p$
