Q.1: Define accuracy and precision. Can we say an instrument of high precision is accurate? Justify your answer.

Q.2: Define "absolute error", "relative error" and "least count".


Q.3: If percentage error in radius of a sphere is 5%, find out percentage error in surface area and volume?


Q.4: Which is most precise in the given readings 4567g, 456.7g, 45.67g, 4.567g?


Q.5: Measured lengths by an instrument are 25.0cm and 10.0cm. Which one is more accurate and why?


Q.6: A rectangular board is measured with a scale having accuracy of 0.2cm. The length and breadth are measured as 35.4 cm and 184 cm respectively. Find the relative error and percentage error of the area calculated.


Q.7: Percentage error in volume of a cube is 9%. Find the percentage error in side of the cube.

Q.8: In an experiment, value of resistances are R1= 5.0 ± 0.2 Ω and R2= 10.0 ± 0.1 Ω. Find out the percentage error in (R1+R2) and in (R1.R2/ (R1+R2)).
