use
g'=g/(1+h/r)^2
where g' is acceleration due to gravity in h km height. and r is the radius of earth
=> 0.2=10/(1+h/r)^2 (let g=10m/sec^2
=>(1+h/r)^2=50
=> 1+h /r=5root2
=> h=6r

abhi178: oky
Hemanth108: this. particulr problem is from. hc. verma 10 class. i am facing difficulty in physics. could ugive me some advice
abhi178: you understand firstly concept then solve example problem. if you feel concetual strength then you solve their exercise . solve all question properly which is simple or hard . I think way your physics is strong. and you will enjoy this subject.
Hemanth108: which. books. r good
abhi178: hc verma ,if your English language strong read resnick heliday book, also if your target jee main and advanced read dc pandey
abhi178: if you want deep knowledge of physics read cinage published B m sharma book
Hemanth108: Thank you. then for. chemistry. and. maths
abhi178: chemistry is enjoying subject in science read understand this by ncert . in physical chemistry RC mukherjee is the best writer. inorganic is memorable subject so for this read only ncert .. math iin higher class is calculus based so, my suggestion you deeply learn calculus .book for math is TMH
Hemanth108: Thank. you. very. much
abhi178: it's my pleaser

The acceleration due to gravity is given by=gravitational force upon any object/
                                                                                                  mass of an object
g=F/m=(GmM/r²)/m=GM/r²

where M=mass of earth,
            r= gaps between the centre of the earth and object and all other                             symbols have their usual meaning.
0.2=(6.62×10^-11)×(6×10^24)/r²
r= 44732538.49 meter

Hemanth108: nice. but. abhi. is correct
