Answer 2

Least count of the spherometer is 0.1 mm .

It is given that :

Number of divisions on the circular scale of spherometer , 50 .

Pitch of spherometer , 0.5 cm = 5 mm .

Now, to find the least cont of spherometer we should know its formula.

Formula to calculate least cont of spherometer is :

$L.C=\dfrac{Pitch}{Number\ of \ divisions}$

Putting value of pitch and number of divisions , we get :

$L.C=\dfrac{5}{50}=0.1\ mm .$

Hence , this is the required solution.
