If radius of earth is R, then the height h at which the value of 'g' becomes one fourth is ................ |
|
Answer» Solution :`implies g/4 = (GM_e)/((R_e+h)^2)` `:. 1/4 ((GM_e)/R_e^2)=(GM_e)/((R_e+h)^2)` `:. (R_e +h)^(2)= 4R_e^2` `:. R_e+ h = 2R_e` ` :. R_e = h` TAKING `R_e` = RADIUS of earth =R h = R |
