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
- A \(11 \%\)
- B 12\%
- C 14\%
- D 8\%
Answer & Solution
Correct Answer
(A) \(11 \%\)
Step-by-step Solution
Detailed explanation
\(\frac{\Delta \mathrm{m}}{\mathrm{m}} \times 100=3 \%, \frac{\Delta \mathrm{v}}{\mathrm{v}} \times 100=4 \%\) Kinetic energy, \(k=\frac{1}{2} \mathrm{mu}^2\) \(\therefore\) Percentage error in kinetic energy,…
