Question

The measured mass and volume of a body are 2g and 5cm^3.with possible errors of 0.01g and 0.1cm^3.what would be error %?

Answer 1

Answer:

m= 2.00 gm V = 5.0 cm

Am 0.01 gm AV = 0.1 cm d = m/V 2/5 = 0.40 gm/cm

$ul a

471

density = d = m/V => Ad /d = Am / m + AV/ V = 0.01/2 + 0.1/5 = 0.025 Ad = 0.025 0.4 = 0.01 gm/cm3

d = 0.40 +- 0.01 gm/cm
