Physics · GRAVITATION
हिन्दीIf the gravitational acceleration at the surface of Earth is \( g \) and the centripetal acceleration of the Moon in its orbit of radius \( R_m \approx 60 R_E \) is \( a_m \), what is the ratio \( g / a_m \)?
Correct answer · Option 4
3600
Explanation
Since gravitational acceleration follows an inverse-square law, g / a_m = (R_m / R_E)^2 = (60)^2 = 3600.
