plzz give me correct answer.....itz very urgent..plzz give me full answer ....​

Answer 1

Explanation:

This answer is for “ At what height acceleration due to gravity decrease to 64% of that at on surface of earth. But if acceleration due to gravity decreases by 64%, then remaining is 36%. Solving in same way as above, we have h = 21.3 × 10^3 KM from surface of earth. whether it's ok for your doubt and I think it would helpful to you
