10. The length I breadth b and thickness i of a block of wood
were measured with the help of a measuring scale. The
results with permissible errors are : 1 = 15.12 2 0.01 cm.
= 10 15 $0.01 cm and t = 5.28 +0.01 cm.

figures is
(a) 0.28%
(b) 0.36% (c) 0.48% (d) 0.64%
11. 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. Then the relative density,

with the maximum permissible error is
W, W₂
(a) 4.00 +0.62%
(b) 4.00 +0.82%
(c) 4.00 = 3.2%
(d) 4.00 -5.62%
