Acceleration Due to Gravity

The percentage decrease in the weight of a body when taken to a height of 4848 km above the surface of the earth is (Radius of the earth is 64006400 km)

Show answer and solution

Answer: (b)

  1. For h≪Rh \ll R: gh≈g(1−2hR)g_h \approx g\left(1 - \frac{2h}{R}\right), so fractional decrease =2hR= \frac{2h}{R}.
  2. 2×486400×100%=1.5%\frac{2 \times 48}{6400} \times 100\% = 1.5\%
  3. So the answer is (b) 1.5%1.5\%.
