Mass and volume of a body are found to be (6.00 0.03) kg and (2.00 0.02) m ^3 respectively. Then the density of a body is
Options
- A(3.00 0.010) kg/m ^3
- B(3.00 0.015) kg/m ^3
- C(3.00 0.020) kg/m ^3
- D(3.00 0.045) kg/m ^3
Correct answer
D. (3.00 0.045) kg/m ^3
Step-by-step solution
Density = M V = 6.00 2.00 = 3.00 kg/m ^3 The maximum fractional error in density is given by = M M + V V 3.00 = 0.03 6.00 + 0.02 2.00 3.00 = 0.005 + 0.010 = 0.015 = 3.00 0.015 = 0.045 kg/m ^3 Thus, the density of the body is (3.00 0.045) kg/m ^3 .
