हिन्दीHow is the acceleration due to gravity at a height \( h \) above the earth's surface approximated for \( h \ll R_E \)?
View Answer & Solution
Correct answer · Option B
\( g(h) \approx g(1 - \frac{2h}{R_E}) \)
Explanation
Using binomial expansion for \( h \ll R_E \), \( g(h) = \frac{GM_E}{R_E^2(1 + h/R_E)^2} \approx g(1 - \frac{2h}{R_E}) \).
