PHXI02:UNITS AND MEASUREMENTS

367460 Assertion :
The error in the measurement of radius of the sphere is \(0.3 \%\). The permissible error in its surface area is \(0.6 \%\).
Reason :
The permissible error is calculated by the formula \(\dfrac{\Delta A}{A}=\dfrac{4 \Delta r}{r}\).

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.

367461 The period of oscillation of a simple pendulum in the experiment is recorded as \(2.63 s, 2.56 s, 2.42 s, 2.71 s\) and \(2.80 s\) respectively. The average absolute error is

1 \(0.1\;s\)
2 \(0.11\;s\)
3 \(0.01 s\)
4 \(1.0\;s\)
PHXI02:UNITS AND MEASUREMENTS

367462 The errors which are estimated by statistical methods are

1 Systematic errors
2 Random errors
3 Theoretical errors
4 Gross errors

367463 According to Joule's law of heating, heat produced \({H=I^{2} R t}\), where \({I}\) is current, \({R}\) is resistance, and \({t}\) is time. If the errors in the measurement of \({I, R}\), and \({t}\) are \({3 \%, 4 \%}\), and \({6 \%}\), respectively, then error in the measurement of \({H}\) is

1 \({\pm 17 \%}\)
2 \({\pm 16 \%}\)
3 \({\pm 19 \%}\)
4 \({\pm 25 \%}\)
