JEE MainPhysicsUnits and MeasurementsMCQ+4 / −1
A physical quantity z depends on four observables a, b, c and d, as z = a2b23cd3{{{a^2}{b^{{2 \over 3}}}} \over {\sqrt c {d^3}}}c​d3a2b32​​. The percentages of error in the measurement of a, b, c and d are 2%, 1.5%, 4% and 2.5% respectively. The percentage of error in z is :
  1. A
    13.5 %
  2. B
    14.5%
  3. C
    16.5%
  4. D
