Errors

If the error in the measurement of the radius of a sphere is 2%, then the error in the determination of the volume of the sphere will be:

1. 4%

2. 6%

3. 8%

4. 2%

In an experiment, four quantities and are measured with percentage error %, %, % and % respectively. Quantity is calculated as follows:

Percentage error in is:
1.
2.
3.
4.

In an experiment, the percentage errors that occurred in the measurement of physical quantities and are , , , and respectively. Then, the maximum percentage of error in the measurement of where , will be:

1.		2.
3.		4.

Time intervals measured by a clock give the following readings:

What is the percentage relative error of the observations?
1. %
2. %
3. %
4. %

A metal wire has mass , radius and length . The maximum possible percentage error in the measurement of density will nearly be:
1.
2.
3.
4.

The errors in the measurement which arise due to unpredictable fluctuations in temperature and voltage supply are:

1.	Random errors	2.	Instrumental errors
3.	Personal errors	4.	Least count errors

A physical quantity is related to four observations and as follows:
