- in an experiment with common balance, the

mass of a ring is

the ring is found to be 2.52g, 2.5g, 2.51g,

2.49g and

2.54g

in successor measurements

calculate

a) The mean value of the mass of the ring

b) Absolute error in each measurement.

c) Mean absolute error.

d) Relative error.

e) the percentage errorâ€‹

Mean value of mass of the ring will be given by –

m = (m1 + m2 + m3 + m4 + m5) / 5

m = (2.52 + 2.53 + 2.51 + 2.49 + 2.54) / 5

m = 12.59 / 5

m = 2.518 gmean mass of the ring will be 2.518 g.

Therefore, the answer is optionÂ a) The mean value of the mass of the ring.
