Q. The dimensional formula of linear charge density $\lambda$ is
Electric Charges and Fields
A
$\left[ M ^{-1} L ^{-1} T ^{+1} A \right]$
B
$\left[ M ^{0} L ^{-1} T ^{+1} A \right]$
C
$\left[ M ^{-1} L ^{-1} T ^{+1} A ^{-1}\right]$
D
$\left[ M ^{0} L ^{-1} T ^{+1} A ^{-1}\right]$
Solution:
Linear charge density $(\lambda)=\frac{Q}{L}$
$\lambda=\frac{[A T]}{[L]}=\left[ M ^{0} \,L ^{-1} \,T ^{1} \,A ^{1}\right]$
