Find the magnitude of acceleration due to gravity at height of 10 km from the surface of earth.

Text Solution

Verified by Experts

`implies` In equation `g_h=g_e(1-(2h)/R_e),h = 10 km = 10^(4)m`
`Re = 6.4 xx 10^(6) m and g_e=9.8 ms^(-2)`
`:. g_(h)=9.8 [1-(2xx10^(4))/(6.4xx10^(6))]`
`:. g_h=9.8[1-0.003125]`
`:. g_h= 9.8 [0.996875]`
`:. g_h=9.769375 ms^(-2)`
`:. g_h = 9.8 ms^(-2)`
