Acceleration due to gravity
- A increases with altitude
- B decreases with altitude
- C is independent of altitude
- D first decreases and then increases with altitude
Answer & Solution
Correct Answer
(B) decreases with altitude
Step-by-step Solution
Detailed explanation
Acceleration due to gravity above the surface (at altitude) is given as \(\begin{aligned} & g^{\prime}=\frac{g}{\left(1+\frac{h}{R_e}\right)^2}=g\left(1+\frac{h}{R_e}\right)^{-2} \\ & g^{\prime}=g\left(1-\frac{2 h}{R_e}\right) \quad \ldots (i) \end{aligned}\) [By binomial…
