An experiment measures quantities a, b, c and x the value of x is calculated from x=a b / c^3 . If the maximum percentage error in a, b and c are 1 %, 1 % and 2 % , respectively, then

Options

  1. Athe error in x may be zero
  2. Bfor any particular reading, error in x may 10 %
  3. Cmaximum percentage error in x is -4 % .
  4. Dmaximum percentage error in x is 8 % .

Correct answer

D. maximum percentage error in x is 8 % .

Step-by-step solution

| x x |= | a a |+ | b b |+3 | c c |
