Physics

Briefly explain different types of errors and their causes. How can these errors be minimised?


SOLUTION

Definition: The measurement error is defined as the difference between the true or actual value and the measured value. The true value is the average of the infinite number of measurements, and the measured value is the precise value.

The error may arise from the different source and are usually classified into the following types. These types are

Gross Errors

Systematic Errors

 Random Errors

Gross Errors

The gross error occurs because of the human mistakes. For examples consider the person using the instruments takes the wrong reading, or they can record the incorrect data. Such type of error comes under the gross error. The gross error can only be avoided by taking the reading carefully.

Systematic Errors

The systematic errors are mainly classified into three categories.

Instrumental Errors

Environmental Errors

Observational Errors

Random errors:- the error which is caused by the sudden change in the atmospheric condition, such type of error is called random error. these type of error remain even after the removal of the systematic error. hence such type of error is called as random errors.

 Minimising errors:

These errors can be minimised by using proper instruments, improving the experimental procedure and removing personal bias.

Q2 Subjective Medium
In Milikan's oid drop experiment on applying a vertically upward electric field an oil drop (of mass $$m$$) moves vertically downward with certain terminal speed.On applying double the electric field in horizontal direction, the drop moves making $$45^{o}$$ with the vertical. Neglecting buoyant forc due dto the air, what is the viscous force acting on the drop in first case?
