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 ........ $\%$

If the error in the measurement of the surface area of a sphere is $1.2 \%$,then the error in the determination of the volume of the sphere is (in $\%$)

Write a note on the combination of errors.

Two resistors of resistances $R_1 = (100 \pm 3) \,\Omega$ and $R_2 = (200 \pm 4) \,\Omega$ are connected in series. The maximum absolute error and percentage error in the equivalent resistance of the series combination are:

The error in the measurement of resistance,when $(10 \pm 0.5) \text{ A}$ current passing through it produces a potential difference of $(100 \pm 6) \text{ V}$ across it,is (in $\%$)

The values of a number of quantities are used in a mathematical formula. The quantity that should be most precise and accurate in measurement is the one
