If nth division of main scale coincides with (n + 1)^th division of vernier scale. The least count of the vernier is (Given, one main scale division is equal to a units)

The length of the rectangle is l = 15.2 cm and breadth is b = 2.9 cm and the minimum possible measurement by scale = 0.1 cm. Then, the area of the rectangle is (Taking significant figures into consideration)

If L, R, C and V represent inductance, resistance, capacitance and potential difference respectively, then dimensions of $${L \over {RCV}}$$ are the same as those of
