There have been suggestions that the value of the gravitational constant `G` becomes smaller when considered over very large time period (in billions of years) in the future. If that happens, for our earthA. nothing will change.B. we will become hotter after billions of years.C. we will be going around but not strictly in closed orbits.D. after sufficiently long time we will leave the solar system.

Answer» Correct Answer - C::D
When `G` decreases with time, the gravitational force `F = (GM m)/(r^(2))` will become weaker with time. Then `r` increases with time. Due to it, earth willl be going around the sun not strictly in closed orbit and after long time it will leave the solar system.
