Solution

The correct option is A $100 g / m m$
$\begin{matrix} Given - & Range of spring balance = (0 - 25) k g For every k g the needle moves by 10 d i v \end{matrix}$
$\Rightarrow 1 k g = 10 div$
$\begin{matrix} Therefore 1 div = 0.1 k g = 100 g Hence least count of the spring Balance = 1 div Reading least count = 100 g \end{matrix}$ $

Least count of spring balance, if a spring balance has a range of 0−25 kg and consists for every kg increment in weight the needle moves by 10 divisions?

The correct option is A 100 g/mm Given - Range of spring balance =(0−25)kg For every kg the needle moves by 10div ⇒1kg=10div Therefore 1 div =0.1 kg=100 g Hence least count of the spring Balance = 1 div Reading least count =100 g $
