An object is suspended from a force meter ('spring balance") capable of reading forces to within +0.01 N. The object is found to have a weight of 4.92 N in air and 3.87 N when immersed in water. (a) Calculate the density of the material from which the object is made. (b) Discuss the reading which could be obtained if the object were suspended from the force meter within an evacuated enclosure. (Density of air = 1.3 kg m, density of water = 1.0 x 10'kgm .) (S)

B14 An object is suspended from a force meter
('spring balance") capable of reading forces to
within +0.01 N. The object is found to have a
weight of 4.92N in air and 3.87 N when
immersed in water.
(a) Calculate the density of the material from
which the object is made.
(b) Discuss the reading which could be
obtained if the object were suspended
from the force meter within an evacuated
enclosure.
