Question

Friends please help me out in getting oys sol^n
Read the statement and answer the two bits (Q No.26)

Answer 1

Least count = 2gf

Zero error = -6gf

a) Stone weight = 48gf-6gf

= 42gf

Weight in water = 40gf-6gf

=34gf

b) weight loss= (48-40)gf

=8gf

Answer 2

Answer:

Step-by-step explanation:

Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument.

 

Example:  

 

Consider a spring balance whose range is 0-25kg.

In its scale, you can see that the 1kg is divided into 10 equal parts. Therefore, the least value it can measure is 100g which can be found out by,

Measurement =1kg

Number of divisions = 10

Least count =1/10 = 0.1kg or 100g

 

100g is the least count of the spring balance. Similarly we can find the least count of different spring balances of different range.
