Question
In the relation F = G ✕ M ✕ m/d2, the quantity G:
Options
depends on the value of g at the place of observation
is used only when the earth is one of the two masses
is the greatest on the surface of the earth
is of the same value irrespective of the place of observation
Solution
is of the same value irrespective of the place of observation
This is because G is constant in the given equation.
