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.


ANSWER

$$(N+1)^{-1}$$ 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? $$(Take f_0 = 325 Hz)$$

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.
