Question

48. Density of substance d = V, where n = (20 +0.2) kg and V =
(10 + 0.1)m. Calculate the percentage error in d
(a) 1%
(b) 2%
(c) 3% (d) 4%​

Answer 1

Answer:

v= (10 + 0.1)m

d= v

percentage error in d,

$\frac{Δd}{d} \times 100 = \frac{Δv}{v} \times 100 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{0.1}{10} \times 100 = 1 \: percent \: error \:$

so, (a) 1% , is the answer.
