Explanation:1. 100g

2.The zero error in a spring balance can be found by suspending it freely. Hold the spring balance in your hand and do not place any weights on it. Note, where the pointer points. If it is zero, then there is no zero error.

(i) Least count of Spring Balance.

(ii) Zero error of spring Balance.

(iii) Least count of measuring cylinder.

$\huge \fbox \red{Answer:-}$

Because the least count and zero error depends upon the instrument. I can only tell you the steps to take out least count and zero error.

_________________________________

Least count of a spring Balance:

• The least count of an instrument is a measure of the least value of an object/physical quantity which can be measured through the instrument.
• The least count of spring Balance depends upon the kind of spring balance you have.
• Least count = 1 unit / divisions between 1 unit.
• If you have a spring balance which has 10 divisions in 1kg it will be 100 gram. If you have the same with 5 divisions, least count would be 200 gram.

_________________________________

Zero error of a spring Balance:

• The zero error of a spring balance is the measurement which comes when the instrument is suspended freely.
• It also depends on the kind of spring balance you have.
• To find out the zero error of spring balance, hold the spring balance freely in your hand and read the marking on it. It will be the zero error of the spring balance.

Least count of a measuring cylinder:

• To find out least count of measuring cylinder, follow the same steps to find out the least count of measuring cylinder.
• It also depend on the kind of measuring Cylinder you have.
