mg' = 2000 N

g' = g[1-(2h/Re)]

g' = 9.8 {1-[2(1800000/6378000)]}

g' = 9.8{1-[2(0.2822)]}

g' = 9.8 { 1- [0.5644]}

g' = 9.8{~0.44}

g' = 4.312

m(4.312) = 2000 N

m= 463.821 Kg

All the units have been used as of mentioned under Standard Convention international .

This answer has a good chance to be wrong because it involved a hell lot of decimal calculation approximations .


vikashkumar8530: I haven't this question answer
omshree22: see, The formula used over here is 100% correct also the method is 100% correct but I am not sure about the calculations part
vikashkumar8530: But here are some numerical value ...
vikashkumar8530: In this these numerical value
omshree22: I have used those values .
vikashkumar8530: Are took
vikashkumar8530: And these value... Where gone
omshree22: I am confident about my answer but the problem is that I have used formula . I don't know whether formula is in your syllabus or not .
