⚫➡A QUESTION FROM PHYSICS SIDE.ATTEMPT YOUR BEST BUDDIES⭐✔☺☟☟⤵
➡WHAT ARE COMBINATION ERRORS+ SYSTEMATIC ERRORS PERSONAL AND LAST LEAST COUNT ERROR. ☺
❎❌NO VERY SHORT ANSWER REQUIRED❎❌⤵☺⭐

Answer 1

Combination of Errors :

1.When two quantities are added or subtracted, the absolute error in the final result is the sum of the absolute errors in the individual quantities.

2.When two quantities are multiplied or divided, the relative error in the result is the sum of the relative errors in the multipliers.

3.The relative error in a physical quantity raised to the power k is the k times the relative error in the individual quantity.

Systematic Errors :
These errors tend to shift the result in one direction.

Personal Errors :
Occurs due to one's own mistake.

Least Count Errors :
Least Count errors arises when the zero of the main scale and zero of Vernier Scale do not coincide.

Hope it helps u!!!

Answer 2

Hey dear !!

So here's u r answer !!

________________________________________________

➡ Combination of Errors :-

↪When two quantities are added or subtracted , the absolute error at last is sum of absolute errors in the individual quantities.

↪Relative error in physical quantity raised to power K is the K times the relative error in the individual quantity.

↪When two quantities are multiplied or divided ,the relative error in the result of sum of relative errors .

➡ Systematic errors :-

↪Systematic errors are those which occur according to a definite pattern . these errors affect the measurement alike i.e. in the same way.

➡ Sources of systematic errors :-

➡ Personal errors :-

↪Personal errors arise due to inexperience of the observer or defect in the eyes of observer . For example lack of proper setting of the Apparatus , reading an instrument without setting it properly , taking observations without observing property precautions etc.

➡ Least count error :-

↪The smallest value that can be measured by a measuring instrument is called the least count of the instrument.

↪For example a metre scale having graduations at 1 mm division scale spacing has the least count of 1 mm or 0.1 cm .

↪Similarly a Vernier caliper usually has the least count of 0.01 cm and a spherometer or a Screw gauge usually has the least count of 0.001 cm.

↪All the readings or values measured by any measuring instrument are good only upto its least count .

↪Thus in the measurement of length , using a metre scale reliability is upto 1 / 10 cm , using a Vernier calliper reliability is upto 1 / 100 cm and using a screw gauge reliability pushes up to 1 / 1000 cm.
