If the length of a cylinder is `l = (4.00 +-0.001)` cm, radius `r=(0.025 +- 0.001)` cm and mass `m =(6.25 +-0.01)` gm. Calculate the percentage error in the determination of density.

The radius of a sphere measured is 4.68 ± 0.01 cm. Estimate the percentage error in the measurement of the volume of the sphere.

The radius of a sphere is (5.3 +- 0.1) cm The percentage error in its volume is

In an experiment to determine the volume of an object, mass and density are recorded as m = (5 pm 0.15) kg and rho (5 pm 0.2)kg m^(-3) respectively. Calculate percentage errorin the measurement of volume.

The volume of a solid cylinder of length 10 cm and radius 4 cm is measured using a vernier calliper which has a least count 0.01 cm. Find the percentage error in the measurement.

Calculate the pH of 0.01 M sulphuric acid.

Calculate the pH of 0.01 M sulphuric acid.

The acceleration due to gravity is determined by using a simple pendulum of length l = (100 pm 0.1)cm . If its time period is T = (2 pm 0.01)s , find the maximum percentage error in the measurement of g.

In a workshop a worker measures the length of a steel plate with a Vernier callipers having a least count 0.01 cm. Four such measurements of the length yielded the following values 3.11 cm, 3.13 cm, 3.14 cm , 3.14 cm. Find the mean length, the mean absolute error and percentage error in the measured value of the length.
