A stone drop from height 'h' reaches at earth surface in 1 sec. If the some stone taken to moon and drop freely from height h then it will reaches at the surface of moon in the time:

  1. $\sqrt { 6 } sec$

  2. 9 sec
  3. $\sqrt { 3 } sec$

  4. 6 sec

A Correct answer
Explanation

Using h = 0.5 * g * t^2, we have h = 0.5 * g_earth * (1)^2, so h = 0.5 * g_earth. On the moon, g_moon = g_earth / 6. Thus, h = 0.5 * (g_earth / 6) * t_moon^2. Substituting h, we get 0.5 * g_earth = 0.5 * (g_earth / 6) * t_moon^2, so t_moon^2 = 6, t_moon = sqrt(6).
