The errors in the measurement of mass and length of the cube is 1.5 % and 2 5 % respectively. The percentage error in the measurement of density of a cube is

Options

  1. A3 %
  2. B1.5 %
  3. C6 %
  4. D9 %

Correct answer

D. 9 %

Step-by-step solution

Density p= m v = m l³ aligned % ser 0 r= P P 100 &= m m 100+3 l l 100 &=(1.5+3 2.5) % &=(1.5+7.5) %=9 % aligned
