Errors in Measurement

The percentage error in the measurement of mass and speed are $2\%$ and $3\%$ respectively. The maximum error in the estimation of kinetic energy is

Show answer and solution

Answer: (b)

$K = \frac{1}{2}mv^{2} \Rightarrow \frac{\Delta K}{K} = \frac{\Delta m}{m} + 2\frac{\Delta v}{v}$
$= 2\% + 2 \times 3\% = 8\%$
So the answer is (b) $8\%$ .
