Vedclass · Answer

(B) We know that the time constant of an $LR$ circuit is $	au = \frac{L}{R}$,which has the dimension of time $[T]$.Also,the time constant of an $RC$ circuit is $	au = RC$,which has the dimension of time $[T]$.Therefore,the expression $\frac{L}{RCV}$ can be rewritten as $\frac{L/R}{CV} = \frac{	au}{CV}$.Since $Q = CV$,where $Q$ is charge,we have $\frac{L}{RCV} = \frac{L/R}{Q} = \frac{[T]}{[AT]} = [A^{-1}]$.Thus,the dimension is $[M^0 L^0 T^0 A^{-1}]$.

$I$ (Fundamental forces in nature)	$II$ (Relative strength)
$(A)$ Strong nuclear force	$(e)$ $10^{-2}$
$(B)$ Weak nuclear force	$(f)$ $1$
$(C)$ Electromagnetic force	$(g)$ $10^{10}$
$(D)$ Gravitational force	$(h)$ $10^{-13}$
	$(i)$ $10^{-39}$
