If one measures the length of an obejct to be 2.70 mm with an instrument of least count 0.01 mm. what is the percentage error in the measurement?

The length of an object was measured to be 30 cm by a linear scale of least count 0.1 cm. what is the % error?

With the help of a graduated cylinder made of ordinary glass, volume can be measured accurately at 10^(@)C . If it is used at 70^(@)C , what will be the percentage error in the measurement? Coefficient of linear expansion of glass =9 times 10^(-6@)C^(-1) .

The potential difference across the ends of a wire has been measured to be (100 +- 5) volt and the current in the wire as (10 +- 0.2) ampere. What is the percentage error in the computed resistance of the wire?

The period of osciIIation of a simpIe penduIum is T = 2 pi sqrt((l)/(g)) . Length l is adout 10 cm and is Known to 1 mm accuracy. The period of osciIIation is about 0.5 s. The time of 100 osciIIations is measured with a wristwatch that shows the minimum intervaI of time as Is (i.e. Ieast count = 1s ). What is the percentage of accuracy in the determination of g?

20 vernier divisions are equal to 19 main scale division of an instrument of vernier constant 0.1 mm. What is the length of its smallest main scale divisions ?

The radius of a right circular cone is measured as 10 cm with a possible error of 0.02 cm and height as 16 cm with a possible error of 0.08 cm. Find the percentage error in computting the volume of the cone.
