- 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 error
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 g
mean mass of the ring will be 2.518 g.
Therefore, the answer is option a) The mean value of the mass of the ring.
