Question

k
The density of a cube is measured by measuring its mass and length of its sides. If the maximum erro
in the measurement of mass and lengths are 3% and 2% respectively, the maximum error in the
measurement of density would be:
A) 12%
B) 14%
C) 7%
The dimensions of Planck's constant equals to that of:
D) 9%​

Answer 1

Answer:

Step-by-step explanation:

Density   d=  $\frac{Mass}{Volume}$

Or   d=  $\frac{m}{a^{3} }$

Percentage error in density  % d= %m+3× % a

⟹ %d=3+3×2=9 %
