The percentage error in the measurement of mass and velocity are 3 % and 4 % respectively. The percentage error in the measurement of kinetic energy is

Options

  1. A11 %
  2. B12 %
  3. C14 %
  4. D8 %

Correct answer

A. 11 %

Step-by-step solution

m m 100=3 %, v v 100=4 % Kinetic energy, k= 1 2 mu ^2 Percentage error in kinetic energy, aligned & k k 100= ( m ~m 100 )+2 ( u v 100 ) & =3 %+2(4 %)=11 % aligned
