367525 A student measures the distance travelled 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, the percentage error in the estimation of \(g\) is \(\left( {s = \frac{1}{2}g{t^2}} \right)\) :

1 \({e_2} - {e_1}\)
2 \({e_1} + 2{e_2}\)
3 \({e_1} + {e_2}\)
4 \({e_1} - 2{e_2}\)
