If `L and R` denote inductance and resistance , respectively , then the dimensions of `L//R` are

Options

A. `M^(1)L^(@)T^(@)Q^(-1)`
B. `M^(@)L^(@)TQ^(@)`
C. `M^(@)L^(-1)T^(-1)Q^(@)`
D. `M^(-1)LT^(@)Q^(-1)`

Answer

B

Explanation

Dimension of `L/R` is same as that of time `(ML^(2)T^(-2)A^(-2))/(ML^(2)T^(-3)A^(-2))=M^(@)L^(@)T^(-1)A^(@)`
