A student measures that distance traversed in free fall of a body, initially at rest in given time. He uses this data to estimated `g`, the acceleration due to gravity. If the maximum percentage error in measurement of the distance and the time are `e_(1)` and `e_(2)`, respectively, the percentage error in the estimation of `g` is

`e_(1)+2e_(2)`

`e_(1)+e_(2)`

`e_(1)-2e_(2)`

`e_(2)-e_(1)`
