Question

At what height acceleration due to gravity will be reduced to 36%

Answer 1

Answer:

4266

Explanation:

g'=g(R÷R+H)^2 using the formula

g'=g÷(1+h÷R)^2 simplying the formula

(36÷100)g=g÷(1+h÷R)^2 solving the value of g' given in question

now simplyfing and solving we get ,

6÷10=1÷{1+h÷R }

10÷6 =1+h÷R

4÷6=h÷R

so,h=2R÷3

substituting value of R= 6400 we get ,h=4266
