ANSWER

(A) In an L-R circuit:

the time constant is R/L so t*(R/L)=[M°L°T°]

The equation comes in the form of e^(-t*R/L)

R/L=[T-¹]

So L/R will be [T].

(B) By Ohm’s law R =V/I, C = Q/v

on multiplying,

RC = (V/I)(Q/V) = Q/I

But Q = It

RC = It/I = t i.e dimesional formula would be [T].

So the unit of RC is second or time constant.

(C) Dimension of L is [ML^2I^-2T^-2] : Dimension of C is [M^-1L^2I^2T^4]

So the dimension of LC is [T^2]

So, the dimensional formula of root LC would be [T].

(D) Dimension of L is [ML^2I^-2T^-2] : Dimension of C is [M^-1L^2I^2T^4]

So the dimension of LC is [T^2]

=>Dimension of 1/root(LC) is [T^-1]

Alternatively, 1/root LC represents resonant frequency in series LCR circuit. So it's unit must be second inverse and hence dimension [T^-1].

Answer:

Dimension of L/C = [ ML^2T^-3I^-2]^2

where [ ML^2T^-3I^-2] is the dimension of resistance.

So, Dimension of L/C = [Resisantce]^2

Here ,L is the inductance and C is capacitance.
