Explanation: \(\text{Hints: } g' = \left(\frac{R}{R+h}\right)^2 g \, \text{অথবা, } g' = g\left(1 - \frac{2h}{R}\right) \\ \text{Solve: } g_h = g \, \text{সূত্রানুযায়ী,} \\ = \left(\frac{6400 \times 10^3}{6400 \times 10^3 + 200 \times 10^3}\right)^2 \times 9.8 \\ = 9.22 \, \text{ms}^{-2} \\ \text{আবার, } g_h = \left(1 - \frac{2h}{R}\right)g \, \text{সূত্রানুযায়ী,} \\ = \left(1 - \frac{2 \times 200 \times 10^3}{6400 \times 10^3}\right) \times 9.8 \\ = 9.1875 \, \text{ms}^{-2} \approx 9.19 \, \text{ms}^{-2} \\ \text{Ans. (A)}\)
