Question

7. The relative density of a material of a body is found by
weighing it first in air and then in water. If the weight
of the body in air is W, = 8.00 +0.05 N and the weight
in water is W2 = 6.00 0.05 N, then the relative density
P = W/(W,- W) with the maximum permissible error
is
a. 4.00 +0.62%
b. 4.00 +0.82%
c. 4.00 + 3.2%
d. 4.00 +5.62%​
