# N divisions on the main scale of vernier callipers coincide with (N+1) divisions on the vernier scale. If each divisions on the main scale of a units, determine the least count of instrument.

$(N+1)^{-1}$ Main scale divisions

##### SOLUTION
Given (N+1) V $=$ NS
LC $=$ 1 MSD - 1 VSD
$= S \displaystyle - \frac{NS}{(N+1)} = \frac{S}{(N+1)}$
$= (N+1)^{-1}$ main scale divisions

Q1 Subjective Medium
In resonance tube experiment, the velocity of sound is given by $v = 2f_0(l_1 - l_1).$ We found $l_1 = 25.0 cm$ and $l_2 = 75.0 cm$. If there is no error in frequency, what will be the maximum permissible error in the speed of sound? $(Take f_0 = 325 Hz)$

Q2 Subjective Medium
Let $I=$current through a conductor, $R=$ its resistance and $V=$ potential difference across its ends. According to Ohm's law, product of two of these quantities equals the third. Obtain Ohm's law from dimensional analysis. Dimensional formulae for R and V are $ML^2I^{-2}T^{-3}$ and $ML^2T^{-2}I^{-1}$ respectively.
