Q76JEE Main 2022 · 25 JUN · SHIFT 1Easy

Acceleration Due to Gravity

The height of any point P above the surface of earth is equal to diameter of earth. The value of acceleration due to gravity at point P will be: (Given g = acceleration due to gravity at the surface of earth).

Show answer and solution

Answer: (d)

  1. h=2Rh = 2R (diameter), so the distance from the centre is 3R3R.
  2. gP=g(R3R)2=g9g_P = g\left(\frac{R}{3R}\right)^2 = \frac{g}{9}
  3. So the answer is (d) g/9.
