Question

the measuring range of a measuring cylinder in 25 ml. If its least count is 1/2 ml, then the space between 5 ml and 10 ml mark should be divided into
a) 25 equal parts
b)10 equal parts
c)5 equal parts
d)2 equal parts

Answer 1

This is a multiple choice question based on practical skills. The measuring range of a measuring cylinder is 25ml. If its least count is 1/2 ml then the space between 5ml and 10ml mark should be divided into Answer:  10 equal parts ( 5 ml = 10 × 0.5 ml)

Answer 2

Answer:

The space between the 5 ml and 10 ml mark in a 25 ml measuring cylinder should be divided into 10 equal parts.

Explanation:

The smallest accurate measurement that can be made with the given instrument is known as its least count. Thus, the least count for an instrument with a scale is the value of one division on the scale.

Here, it is given that the least count of the measuring cylinder is 1/2ml.

Let 'X' be the number of divisions.

Thus, the space between the 5ml and 10ml mark should be divided into:

Least count = $\frac{final reading - initial reading}{number of divisions}$

i.e. $\frac{1}{2}$ = $\frac{10 - 5}{X}$

Therefore, X = 10

Thus, the space between the 5 ml and 10 ml mark should be divided into 10 equal parts.
