1.	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` isA. `e_1 + 2e_2`B. `e_1+ e_2 `C. `e_1 - 2e_2 `D. `e_2 - e_1`
Answer» Correct Answer - A `h= (1)/(2) "gt"^(2) ` (for free fall) `g= (2h)/(t^(2)) rArr (Delta g)/(g) = (Delta h)/(h) + (2Delta t)/(t) = e_1 + 2e_2`
