A body travels uniformly a distance of (20 0.2) m in a time (4.0 0.4) s. The percentage error in the value of velocity is

Options

  1. A8 %
  2. B11 %
  3. C4 %
  4. D16 %

Correct answer

B. 11 %

Step-by-step solution

Velocity is given by v = s t The percentage error in velocity is v v 100 = ( s s + t t ) 100 Substituting the given values: v v 100 = ( 0.2 20 + 0.4 4.0 ) 100 v v 100 = (0.01 + 0.1) 100 = 0.11 100 = 11 % Answer: 11 %
