Motion in a Straight LineMedium
A student measures the distance traversed in free fall of a body, initially at rest, in a given time. He uses this data to estimate g, the acceleration due to gravity. If the maximum percentage errors in measurement of the distance and the time are $e_1$ and $e_2$ respectively, then the percentage error in the estimation of g is
1. Option A: $e_2-e_1$
2. Option B: $e_1+2e_2$

4. Option D: $e_1-2e_2$
Show answer & explanationHide answer & explanation
Correct answer: (B) $e_1+2e_2$
Explanation
For free fall: $h=\frac{1}{2}gt^2$ Therefore, $g=\frac{2h}{t^2}$ Maximum fractional error: $\frac{\Delta g}{g}=\frac{\Delta h}{h}+2\frac{\Delta t}{t}$ Hence percentage error: $e_1+2e_2$
